Boston Marathon 2022: Running my heart out

I ran my 4th Boston Marathon yesterday which was my 31st lifetime marathon. It was an amazing experience and I am so thankful that I was able to complete it, given everything that has happened to me during this training cycle.

A common question asked on race weekend is "How many Bostons have you run?" And I never knew if I should say 2 or 3, because it depends if you count the 2020 virtual. I definitely count it as a Boston, but in terms of running the official course, I had done that just twice before. So yesterday was my 3rd time on the Boston course, but my 4th Boston Marathon. 

Training Cycle Recap
Due to having Covid in January (24 days off), and getting injured at the end of March (9 days off) I was only able to consistently train for six weeks: from February 5 to March 24.

My long run progression was as follows, starting with February 11: 10 miles, 14 miles, 17.5 miles, 18 miles, 20 miles, 18 miles, 12 miles (was supposed to be 23), 15 miles.

My weekly mileage gradually climbed up to 70, with everything feeling great— until I hurt my SI joint during a deadlift. Oh the irony of strength training to prevent injuries. . . only to have it cause an injury! In retrospect I should have gotten my lower back checked out sooner and taken a few days off after it happened, but since it was so minor initially, I thought it was just a small niggle that would go away.

Post-Covid Heart Rate
I don’t think I lost much fitness after taking 24 days off for Covid. The first few runs back were hard, but after about 2 weeks I was hitting my normal training paces. My resting heart rate remained elevated for about 80 days, but eventually normalized about three weeks ago. My heart rate while running was consistently 8-10 BPM higher than normal, but the paces felt normal. 

December 16 easy run with avg. HR per mile


Feb. 28 easy run with avg. HR per mile

This is just one example of how my easy run HR was about 8-10 beats per minute higher post covid. Post covid, my easy heart rate is in the low 160s, whereas before covid, it was in the low 150s. I run based on effort, not pace, so my effort level matched the pace post-covid (a 7:00 pace felt like a 7:00 pace), but the heart rate would be much higher post Covid. 

The same was true for tempo runs. My heart rate for those post-covid was in the high 170s, and before Covid it was in the high 160s.

I simply brushed this off and thought it would eventually come down. If I didn't train with a heart rate monitor, I would have had no idea that anything changed. I certainly never expected this to impact my marathon because it hadn't impacted my training or how I felt running. I had plenty of energy while running, my breathing felt normal, and nothing seemed off. 

Before the Race
I slept about as well as can be expected the night before the race. From about 8:45pm to 1:00am, and then off and on until I was up for good at 4:30. I didn’t have as many pre-race anxiety dreams as I usually do, which was nice. I prepped my bag to bring to athletes village, got dressed, pinned on my bib, drank a good amount of water, went to the bathroom a few times, and then was off to meet my friend Deanne.

I met Deanne halfway between our hotels and it was a very short walk to the busses. We were in the same corral and it was her first Boston. I had met her at the Rehoboth Beach marathon last winter and we talked about how we would both be running Boston with a similar qualifying time. We were both in Wave 2, corral 5, which had a bus loading time of 7:30 and a start time of 10:25.

Greg walked with us to the busses, hugged me goodbye and it wasn’t long before we boarded. The bus ride was very bumpy. There were times when I felt like I would be knocked out of my seat. But otherwise it was uneventful and it went by quickly with Deanne as company. We both ate our breakfast. I had a bagel with almond butter and it went down really well. I didn’t have my typical pre-race butterflies. I wasn’t putting any pressure on myself for this race and it was nice to be able to eat a whole bagel without my stomach feeling off. 

Once we arrived in Athlete’s village, we hung out with a few other runners, used the Porta potties many times, applied sunscreen, and adjusted our shoe laces. 

After my horrible GI experience in Harrisburg in the fall of 2020, I finally decided to give UCAN another try as my pre-race fuel. I had been using it during training and I have had so many races where UCAN worked well for me. Plus, I switched from the lemon flavor to the orange flavor and it seemed to have a smoother and more airy texture.

I slowly drank my bottle of about 1 and 1/3 packets starting 40 minutes pre-race and continuing until 25 minutes pre-race. It went down very easily and I had no problems whatsoever. I carried my own water bottle so I could avoid crowded water stations in the beginning and ensure that I got enough fluids early in the race. Deanne and I made our way to the start line, and we ditched our outer layers along the way.

Weather
It was about 45 degrees and sunny in Athlete’s village. There was no cloud cover until about 15 miles into the race, at which point it became just partly cloudy. The temperature wasn’t supposed to rise to more than 52 degrees, and it would actually get cooler as we ran into Boston with a 10mph headwind in the last 10K. 

I think this is probably the best weather Boston has had in nearly 10 years. Of course my ideal is about 10 degrees cooler, but I think this is probably as good as it gets for Boston! So it gets an 8/10 on my race weather scale. A 7:00 start time would have made for a 10 out of 10!

Race Strategy
My plan was to start out at a pace of around 7:45 and gradually speed up if I felt good. I wanted to give myself a shot at a course PR (sub 3:26:54) so I planned to get to the halfway point at 1:41:00. That would put me on pace for a time of 3:22, but I knew I would be slower in the second half, and hopefully I would finish at around 3:25.

The pacing strategy was there to ensure that I didn’t go out too fast. If it felt too fast or if something was hurting, I would certainly back off. I mostly wanted to run a steady effort - faster on the downhills and slower on the uphills. I didn't want to box myself into a very specific pace, but I also needed a plan so I wasn't just winging it. I made sure to use the official mile markers as my reference point, not my Garmin auto lap. 

Miles 1-6
Deanne and I arrived in our corral and it wasn’t long before our wave was released. I felt like I was running at a very easy pace, as the first mile was mostly downhill and my legs were fresh. These miles were quite crowded so I made sure not to do too much weaving. I typically end up with 26.5 miles on my Garmin at Boston because I don’t run the tangents. I needed any advantage I could get during this race so I tried to run in a straight line unless I absolutely needed to pass someone.

My top priority was to enjoy the race and not be too inwardly focused that I missed out on what was happening around me. I did look at my Garmin fairly regularly to ensure that the hills weren’t taking me out too quickly. It was definitely warmer than I would have liked, so I poured an entire cup of water over my head at each water station. Thankfully it wasn’t at all humid! I couldn’t believe that some people were wearing long sleeves. I would have baked!

On my arm, Greg had written 39:00 as my target 5-mile split. I hit that almost exactly— I think I was about 10 seconds ahead. I drank from my water bottle every 15 minutes, and didn’t take any additional fuel until the 1:00 mark, at which point I had 2 honey stinger chews. The UCAN lasts for about 90 minutes, but I wanted to give myself a little extra fuel while my stomach was still easily digesting things.

Mile 6: 7:32

Miles 7-11
My official 10K split was 48:10, which is a pace of 7:45. Exactly what I wanted. Soon it would be time to see Greg. He took the Commuter Rail out to Natick and told me he would be positioned shortly before mile marker 8 on my left side. I definitely did not want to miss him so starting at mile 7, I stayed to the far left side of the course and looked at all the spectators. I spotted him before he spotted me and I yelled out his name. Thankfully he saw me in time to shoot some photos!

Greg's photo at mile 7.8
Seeing him was so amazing, as I had not been able to see him during my first two Boston Marathons. During the first one, I missed him entirely. During the second one, it was ridiculously rainy so I told him to hang out in the hotel and meet me shortly after finishing.

My mile 10 goal was 1:17:30 (7:45 average pace). I was about 25 seconds faster as I passed the mile marker, but I was okay with that, given how great I felt. I figured I might want to hold back slightly until I reached the Newton hills. I took a Maurten gel at about 1:20 and continued to pour water over my head at each station. It got in my eyes a few times, so I learned that I needed to close them as the water fell down my face. I think I stopped pouring the water on myself somewhere around mile 11 or 12. The sun didn’t feel as strong and I felt more comfortable temperature wise. I was thankful that it didn't get any hotter and I think the warmest miles were actually the first 10.

Overall, these early miles felt amazing. I still felt like I was running my easy pace and I knew I was going to have an amazing day. My legs had no fatigue yet. My SI joint wasn’t bothering me at all. Everything felt loose and smooth and I was completely relaxed.

Mile 9: 7:34

Mile 11: 7:42

Miles 12-16
This was the last stretch of the race before the infamous Newton hills! I was elated that I had made it so far and I knew that even if my SI joint acted up I would at least be able to finish. And really, that was all I wanted: to finish and get the medal. I wasn't at all worrying about my finish time or pace or anything other than the fact that I was in this race and I was going to finish Boston!

The last time I had run this course, rain was coming down in buckets and wind was pounding me in the face. I was carrying at least 5 extra pounds of weight with my added clothing and wet shoes. It felt amazing to have gorgeous weather and to truly appreciate my surroundings. 

I knew that there were probably hundreds of people tracking me. Based on the comments I had received on my Instagram posts as well as direct messages, I definitely felt like I had an "audience" for this race. Even still, every time I crossed a timing mat, I mostly though of Greg, who was waiting eagerly for those splits to come in. I wanted him to know that I was safe and that I was running strong. Every time I crossed a timing mat it was like I got to communicate with him.

My official half marathon split was 1:40:51. Wouldn't it be such a fast half marathon if we could run the first 13.1 miles of this as a half marathon race!? I was 9 seconds ahead of target and I felt like I had plenty of gas left in the tank. I was in great shape. I did notice a mild pain in my left chest, around my heart area, but cramps often come and go during marathons, so I didn't focus on it. 

The race didn't start to get hard until the 14th mile, and even at that point, it just felt a little harder. Exactly how it's supposed to feel during a marathon. I still had my chest pain, but there was nothing I could do about it, so I continued to run normally.  

There was now a slight headwind but it helped cool me down so I no longer felt too hot. There were enough people to draft off of that if the wind got too bad, I would just tuck behind a pack like I did in 2018. I had my second Maurten gel at 2:00 and it went down easily. At this point, I had ditched my handheld bottle and was drinking from the cups.

Miles 17-21
The Newton hills had arrived! Thankfully, I had not killed my quads on the downhill and my legs were ready to make their way over these 4 monster hills. During the 17th mile, as I was climbing a Newton hill I suddenly felt like I was running at 5K effort. My legs were moving relatively slowly up the hill but that pace felt completely unsustainable from a heart rate perspective. It was as if the effort level suddenly skyrocketed and my heart rate was off the charts high. I needed to walk for a few seconds to bring that heart rate back down. 

Staying Strong at 30K
As much as it pained me to go from the 7:40s to walking, it was what I needed to do to feel normal again. It was weird how marathon effort turned into 5K effort just by going up a hill. I resumed running after a quick walk break, but it was a very slow run. I told myself just to get up the hill and everything would be okay on the way back down. And it was. I felt totally normal again on the downhill and it was as if I never needed a walk break. 

And then the next hill came. This one wasn't as much of a struggle as the first and I made my way up it slowly without having to stop. I didn't feel my heart rate surge as much, although I definitely knew it was getting up there. Probably around 10K effort. 

And then back down the hill and everything was fine. The next two hills were nearly impossible! I had no idea why this was happening. I had a good amount of energy. My legs were tired but they weren't hurting and they could certainly climb. But yeah, it was like running a 5K or a 1-mile race with how much cardiovascular effort I was putting out. 

My official Heartbreak hill split (mile 21) was 9:40 according to the tracking app. That's my SLOWEST Heartbreak Hill of all three Boston Marathons. Slower than in 2016 when I ended up in the medical tent from overheating. I remembered 2016 when I was bonking hard core due to the heat and how much I struggled to get up the hill. This was a totally different kind of struggle. My legs back in 2016 felt like knives were going through them. The pain was unforgettable! But yesterday, my legs were totally cooperative! I just didn't have the cardiovascular strength to get up the hill. "Heartbreak Hill" has a WHOLE new meaning for me now. It almost literally broke my heart!

Mile 17: 8:34
Mile 18: 8:28
Mile 19: 8:20
Mile 20: 8:39
Mile 21: 9:40

As this was happening to me, I didn't get discouraged. I just did what I could to get up the hill safely. I am unable to see my heart rate while running, but I do have a wrist HR monitor in my Garmin that is usually pretty accurate so I can look at the data afterwards. Even though I couldn't see my HR, I just knew it was out of control. (I would later find out that my average heart rate for these miles was 175-188, which is what I would expect in a 5K).

Combined with the chest pains, which had mostly subsided by this point, I definitely suspected my heart was not fully recovered from Covid. I had just never put this much strain on it to know its limitations. I could easily get away with 10 miles at marathon pace in workouts and having my heart rate be 10 BPM higher than normal. But after 16 of those suckers and then going uphill. . . NOPE!

Miles 22- Finish
While it was discouraging to have slowed down, I reminded myself that each races has its highs and its lows and just because you go through a difficult stretch during a marathon, it doesn't mean you can't bounce back and run strong again. Just because I had to walk up part of the hills didn't mean I had to continue with walk breaks for the remainder of the race. 

Now the goal was to finish strong, have fun, keep smiling, and keep the heart rate at a level that was sustainable without having to stop and walk. I figured I could still salvage a BQ (sub-3:40) so I would try my best to do that. My legs had a lot of pep left in them and I had a good amount of energy. I was happy and determined. But if I pushed any harder than around an 8:30 pace, it would start to feel like a 5K again.

This was the time to dig deep, to stay positive and remind myself I was running the Boston Marathon. I had to run the 2020 Boston on a trail near my house and this was a million times better! I was surrounded by amazing runners and thousands of enthusiastic spectators. I let this sentiment carry me and I had a perma-smile on my face all the way into Boston.

When the flags appeared that said "Boston" at mile 24, letting us know we had made it into the city, I got a little choked up. I had made it to Boston. Safely and without my SI joint injury stopping me. I was so grateful. I had so much to be thankful for that the slow down didn't even faze me. I chalked it up to my heart not being 100% post covid and I would deal with that later. 

I knew to expect Greg at around mile marker 25 on my right. I made sure to stay to the right of the course and I looked at all the spectators, searching for his bright yellow jacket and white hat. I wanted him to see me looking strong and having the time of my life. I was so happy when I finally got to him! I knew I was going to make it and he knew I was going to make it. And it wouldn't be long until we could celebrate my finish together!

Less than a mile to go

As I made the final turn onto Boylston I had so much energy. The adrenaline was insane and I felt like I could have run forever! This was the grand finale that dreams are made of. I later found out that I ran my fastest ever mile 25 and mile 26! So even though my time was slower than 2018, I was faster in the final miles.  Here is a photo of me running down Boylston:

Pure Joy!
Mile 22: 8:32
Mile 23: 8:46
Mile 24: 8:41
Mile 25: 8:36
Mile 26: 8:47
Final 0.42: 7:49 pace

The Finish
Speaking of photos, one of my goals for this race was to finally get a good finish line photo. In previous years, I was blocked by so many other runners that you can't get a good view of me. I was also wearing hats in the previous two races so the aerial shots didn't work great. This year, since I was not on the verge of hypothermia or heat exhaustion, I had the mental capacity to strategically place myself when crossing:


I got my finish line photo!

I think more will be posted soon, and when they are I will add them to this blog.

My official time was 3:33:04. This is a BQ by nearly 7 minutes! I didn't get a course PR but at least I finished with a very respectful time. Especially when you consider that I was only able to train for six weeks! It's also crazy to think that I ran 6 minutes faster in a torrential downpour with a 25mph headwind back in 2018. It gives me even more respect for my previous self! 

After crossing the finish line I noticed that I didn't need to vomit. This is my first marathon in about 5 years where I haven't vomitted or dry heaved at the end. I attribute it to being relaxed and not pushing to my max. I had to keep that heart rate under control.

I walked through the finish line area, got my medal and my heat sheet and met up with Greg at our pre-determined meeting spot. He had got there before me, even though he walked all the way from mile 25.2 and I ran. That's because my walk through the finish area was very, very slow. I also stopped to talk to a few people along the way. I was elated when I finally met up with him and together we walked about half a mile back to the hotel.

On the way back to the hotel, I told Greg that the limiting factor wasn't my SI joint or my hip or my foot. . . it was my heart rate. I told him about the chest pains around my heart and the feeling of running 5K effort when going up hill. 

At the hotel, I immediately uploaded my data to my phone and looked at my heart rate. Sure enough, it was elevated throughout the entire race. I averaged a heart rate of 171. During the Newton hills it peaked at 198, and it even averaged 188 for one of the miles. Usually I only see that kind of heart rate when I'm racing a 5K in the heat. 

I called my coach and she suggested that I look at heart rate data from my previous marathons. Sure enough, I was consistently averaging 163-164 for those (at a significantly faster pace). My half marathons typically average around 169. 

By mile 6 of this race I was already averaging a 173 heart rate per mile

Mile 6: 173
Mile 7: 173
Mile 8: 178
Mile 9: 174
Mile 10: 174
Mile 11: 175
Mile 12: 175
Mile 13: 174
Mile 14: 176
Mile 15: 188
Mile 16: 178

When I ran my Turkey Trot PR back in November, my mile-by-mile HR was 170, 181, 182, 173, 174, 173, 173. And that race averaged a pace of 6:35.

Even though it felt like marathon pace effort, my heart was beating at 10K effort. And I knew this before even looking at the data. So I will be seeing a sports cardiologist later this week. I really hope that nothing is permanently damaged in my heart and that things will eventually go back to normal. I can be patient if I know that normalcy is coming. Because if this is my new-normal, then I can say goodbye to PRs at any distance. Sure, I can hit my training paces, but it won't be possible to go all-out in races. 

Final Thoughts and Key Takeaways
I did it. I ran Boston! After all the obstacles I faced this cycle, I made it to the start line healthy and I powered through 26.2 miles of joy and celebration. I earned my 4th Boston medal. I got another Spike unicorn. I have another jacket. Another bib to display. My fastest ever run down Boylston! My best finish line photos! There's so much to celebrate and to be thankful for. A 3:33:04 in Boston is a huge achievement and I am so proud of it!

My fueling plan worked, I had no GI distress. My legs didn't give out on me and I am less sore than I was at my previous two Bostons. Did I push to my max during the final 10K? No. I did what I could safely sustain. Heart stuff can be serious, but I am not going to freak out yet. I am going to assume that my heart just needs time to heal and all will go back to normal eventually unless my doctor tells me otherwise. I haven't had any heart symptoms since the race.

Ranking:
Overall 11260/24819
In Gender 2962/10563 (Female)
In Division 499/1634 (F40-44 Age Group)

Top 500 Age Group is really good for Boston! This was also my first Boston Marathon as a 40+ year old. I was 39 back in 2018. I'm also in the top half of all runners, which is nice to see. My bib number was 12827 and I placed 11260, and I always love beating my bib number. 

I will either return to Boston in 2024 or 2025. Greg will be 45 in 2025 which means he gets 10 extra minutes onto his qualifying time (3:20 vs. 3:10). So if he qualifies, I will wait to run it in 2025. If not, I will likely go back in 2024. Either way, I am definitely not done with Boston! More to come.

Fort Hunt 10K Race Report

This morning I ran the Fort Hunt 10K in Alexandria, Va. Although government officials in Northern Virginia are still denying permits to race directors, this race was a go because it took place in a park and didn't require any road closures. And it was super small. The 10K had 18 finishers and the 5K had 51 finishers. 

Small as it was, this race was not without stiff competition. Some pretty serious athletes lined up at the start line.

Before the Race
This race had been on the calendar for about a month. I ran a 5K exactly one month ago in the Outer Banks, and I typically like to do one race per month. My training volume has picked up and I've logged some solid workouts, so I felt like I was in shape to run a solid 10K. My average pace for that 5K was 6:59 due to the extreme heat. I thought it would be a good accomplishment if I could turn that into my 10K pace today.

Greg and I got a late start. Typically I wake up between 5:00 and 5:30 without an alarm. I set my alarm clock to 5:45 as a backup on the off chance that I would sleep late. And sure enough, the one morning I sleep late, that's when the alarm goes off! Realistically, I thought I would be awake at 5:30 and have nearly an hour to get ready. But that was not the case.

We quickly got dressed, ate our English muffins with peanut butter, went to the bathroom, got our water bottles ready and off we went. The plan was to leave the house at 6:25, but at 6:20, Greg had just started making his coffee! Thankfully we were pretty quick about everything and left the house at 6:35, only 10 minutes later than planned. That said, I had underestimated how long the drive would be. I had assumed 35 minutes but it was actually 45 minutes. 

With a 7:45 race start, we were cutting it very close. We arrived at 7:15 and immediately headed for the park bathrooms. If you ever run in Fort Hunt, I do not recommend you use the indoor bathrooms. There were mosquitos everywhere. And moths and spiders. And the bugs were in the toilets, on the stalls, flying around. It was disgusting. 

After using the bathroom, we picked up our bibs and shirts. It was now 7:25, which meant we had 20 minutes to pin on our bibs, warm up, and use the bathroom a final time (I opted for a porta-potty and it was far more pleasant). For this reason, my warm up was only 0.8 miles. I wasn't too worried about it though, because I typically opt for a much shorter warm up when it's warm/humid.

Race weather and strategy
Speaking of weather, it was 70 degrees with 94% humidity, overcast, and a little bit of wind. Typically I do not run any longer than a 5K in conditions like these. I usually wait until October to run a 10K, but I couldn't find any 10Ks in October as my usual options were canceled. Given that I got mono two days after a 5K in similar conditions back in 2018, I was a little apprehensive about this situation. The last thing I needed was to end up sick with mono again after having avoided it all summer.

So my strategy was to run by effort. I threw all my time goals out the window. Humidity is deceptive, especially with overcast skies. It doesn't feel oppressive at first but then it sneaks up on you. I have many examples of humidity related bonks; both in workouts and in races. I did not want a repeat. Top of mind was a 10K I ran in February of 2019 out in Arizona. That race as 58 degrees and very humid and I crashed and burned my way to a time of 44:29, which was 3 minutes off of my goal!

I approached this race very cautiously for those two reasons: not wanting to get sick, and not wanting to crash and burn. The goal was even splits or negative splits. Even slightly positive splits would have been fine as long as it wasn't a total bonk. Anyway, the race course was 5 loops of Fort Hunt Park. It was a completely paved road with gently rolling hills throughout. This struck me as a very fast course because none of the hills were too long or too steep. Just enough to get some good variation and that wonderful downhill relief from time to time.

Miles 1-2
The race started and I noticed a woman bolt out ahead of me at lightening speed. I definitely did not try to follow her. Given what I know about the deceptiveness of humidity, I thought I could possibly catch her later on if she had mis-judged the impact of the conditions and gone out too fast. Greg had also gone out like a lightening bolt. So fast I thought he might even lap me!

I had not run at Fort Hunt park since January 2010 during the epic blizzard we had that winter. Fort Hunt Park was the only plowed surface I knew of that was run-able so I had gone there twice for my long runs. It's a loop of about 1.25 miles and as I said earlier, it's gently rolling with the hills being short and not terribly steep. I suspected that running 5 laps around would be mentally exhausting but it turned out not to be. I liked knowing what to expect each lap.

I started at what felt like half marathon effort. I viewed this as a long tempo run. In fact, I didn't even wear my fastest shoes. I didn't wear the Nike Vaporfly and I didn't wear the adidas Adios. I wore the adidas Tempo 8, a shoe that has been discontinued, because it's a good half marathon shoe and I wanted to approach the race as. . . a Tempo!

I lost sight of the woman ahead of me after only 3-4 minutes. And by the end of the first mile, I had given up all hope of catching her. She had such a large lead that I'd have to really speed up and/or she would have to really slow down. 

Mile 1: 7:11
Mile 2: 7:12

Miles 3-4
I was pleased that I was holding steady for the first two miles. I would have liked the splits to have been faster, but I knew that I was going at a pace that would set me up for success later in the race. Thus, when my Garmin beeped 7:02 for the 3rd split, I was really excited. In fact, that third mile went by so quickly I could hardly believe it when my watch beeped. 

I didn't consciously increase my effort level, but I definitely did. When I run long runs, I usually don't try to speed up, but I do so naturally if I'm having a good day. The same thing was happening here. Without even trying to put any more effort into the race, my pace was getting faster. I was shocked when mile 4 beeped in 6:54.

Mile 3: 7:02
Mile 4: 6:54

Miles 5-6
Could I hold onto this pace? I didn't think I could but once again, my focus was not on pace but on effort. I started to tire in the 5th mile, but I reminded myself that this was a race and I needed to press on and keep working hard. I told myself to relax and focus on my form. I thought back to all my strength training sessions and I told myself that even though I was tired, my legs were the strongest they have ever been so they would power me through.

About halfway through the last lap, I saw the leading woman up ahead. And I realized I was closing the gap. I tried to think of a strategy for passing her, but my mind was too busy convincing myself to push hard to come up with a sound plan. The easiest thing would simply be to maintain my pace because at this rate, I would catch her and pass her. The unknown was if she was crashing or if she had a second wind in her.

I maintained my pace, which was around 7:00 and that allowed me to catch up to her and run beside her with about half a mile to go. As soon as she noticed me she pulled ahead. With a half a mile to go, I wasn't ready to surge yet, so I hoped that she would fade and then I would surge ahead in the last 0.2. But she pulled farther ahead and as much as I tried to keep up with her, I could not. And admittedly, I didn't have my usual motivation to win. Mentally I was in "hard workout" mode and I couldn't easily shift into race mode.

So she ended up winning by 4 seconds! So close!

Mile 5: 7:07
Mile 6: 6:59
Last 0.2: 6:26 pace

After the Race
My official time for the race was 43:37. This is an average pace of 7:02. The winning time was 43:33. Given that there were only seven female competitors, I'm not loving that I placed second. But, that first place female was a force to be reckoned with for sure! And she was under 40, so I technically won my age group.

Greg set a PR in 40:20. This is a PR by about 30 seconds. I am not surprised because he has gotten WAY faster over the past year. The key to his success has been consistency and volume. I'm his coach, and by prescribing him more mileage with less speed work, he is less prone to injury. If he can run a time of 40:20 in these conditions, I definitely think he can qualify for Boston later this fall if the conditions align. He placed 4th overall. There were only 11 male competitors, but they were all really fast.

Greg and I cooled down together and we went to visit the horse that we saw along the way. What a beautiful animal! Our cool down was 1.5 miles, and I wasn't dying.

Final Thoughts and Key Takeaways
My heart rate data shows that I worked really hard today and supports my assertion that my body does not tolerate humidity. Here are the average heart rates for each mile: 144, 168, 172, 176, 181, 192, (195 for the last 0.2). Normally my heart rate would be more steady. 

To compare, here is heart rate data from a 10K that I ran earlier this year in cold weather: 145, 170, 174, 174, 174, 172 (172 for the last 0.2). Looking at other athletes' heart rate data from today on Strava, they do not have the same heart rate drift that I do. I know I shouldn't need to validate my humidity/heat sensitivity this way, but it's always nice to have data that supports why I run so much slower in these conditions.

I think I had a really good day! Normally in these conditions I feel like I lack energy and like I am running through molasses. But today I felt strong and I ran a solid race and I achieved my goal of a negative split. I do think that if I had gone out at a pace of 6:55 the story would have been different. Here's why I think I managed the humidity well:

  • I drank plenty of water and UCAN Hydrate in the days leading up to the race
  • I slept well the night before the race, as evidenced by the alarm waking me up at 5:45
  • I was acclimated to the humidity, but not run down by it due to using the treadmill on the worst days.
  • Pacing, pacing, pacing. The conservative start was critical.
  • Attitude. I didn't put any pressure on myself to run a certain time. Instead, I had a process and a strategy and I executed it.
  • Strength training. I believe I run more efficiently now, so I didn't tire as easily as I otherwise would have.
My next race will be a half marathon in three weeks. If conditions are good, I can turn this 7:02 pace into my half marathon pace. Funny enough, that still wouldn't even be a PR! I'd need to run a 6:54 pace to PR a half marathon. Onward!

Battling My 10K Demon

I've blogged about this many times before: the 10K is my weakest distance. I think I finally have a physiological explanation why. It doesn't make sense that I can run a half marathon at about the same pace as a 10K, but maybe it's starting to make sense.

I ran the Veteran's Day 10K today. It was in the low 50's and sunny and the course was flat. These are arguably perfect racing conditions, although I would have preferred more cloud cover. I had run this course twice before-- in Oct. 2008 and Dec. 2007. My PR was set on this course in Dec. 2007 at 49:23. Since then, I had run many 10Ks that were pretty much equivalent to that, despite my fitness getting remarkably better over the past two years.

I decided that no matter what, I needed to get a PR today. I have had six weeks of training since my injury so I had no idea what kind of shape I was in. But even though I am not where I was pre-injury, there is no reason why I shouldn't have been able to break that soft PR. My strategy was to start out at a pace of 7:50 and then gradually speed up if I felt that I could. I was aiming for a PR by about 45 seconds, although I knew I was capable of faster based on some recent training runs.

Mile 1: 7:46
Mile 2: 7:48

These miles felt easy. I could hardly believe I was going at this pace for how easy it felt. I was afraid to run faster, though, and I told myself I would really hammer it home on the second half if I continued to feel this good. During the first mile, my boyfriend ran ahead of me. This surprised me because his goal was to run a 7:45 pace, but he ran ahead at what must have been a 7:30 pace.

Mile 3: 7:52 (includes water station)
Mile 4: 7:48

It started to feel difficult and I kept looking down at my HR monitor wondering why my heart rate kept reading 181. It should have been reading 184-185. I knew I wasn't putting forth a true race effort based on my heart rate, but it felt really difficult and I decided that I would save it for the last mile because I didn't want to push too hard too soon.

Mile 5: 7:55
Mile 6: 7:57

I gave it everything I had during the last mile, but all I could muster was a 7:57. I just didn't have the energy to push any harder. I wanted so badly to get a 10K time that reflected my true abilities, but it just wasn't happening. I looked down at my Garmin as I saw the finish line. I had to make it there under 49:00. I dug as deep as I could and found a 7:22 pace for the last 0.2 and my heart rate finally got up to 184, which is where it should have been for the entire race.

My average heart rate for this race was 180. It should have been about 185. I ran the entire race in my "lactate threshold zone" which is considered your 15K or 10-mile pace. I got a great tempo workout in but I didn't actually "race" this 10K. It wasn't like I didn't try. . . I just didn't have the energy to get up where I needed to be. I keep asking myself if I had run the race based on HR and not on pace if I would have fared much better, but I am just not sure I could have actually maintained a 185. I wouldn't be surprised if I maintained a similar heart rate for my upcoming half marathon.

This is something I am going to ask my coach about: why can't I find the energy to get my heart rate (and speed) up to where it should physiologically be for a 10K? I can get my HR where it needs to be for all other distances-- even the 5K! But for some reason, this 10K just kills me every time.

I am happy that I set a PR, and I feel like I ran it as hard as possible. The evidence being that I faded during the last two miles. Maybe next time I go out at a pace of 7:35 and fade down to a 7:50. Establish that I am going to be at a higher heart rate early on and just stick it out. My boyfriend ran a 46:56, which is a four-minute PR.

Finish time was 48:54, a PR by 29 seconds.

I placed 19 out of 205 in my age group. This is the top 9th percentile, whereas I usually find myself in the top 5th percentile for other distances.

Up next: Turkey Trot 5K. Goal is 23:10.
