mantra to relax. However, beginning at the second fluid aid station I noticed the pacing leaders dramatically speeding-up afterward for a mile which was both annoying and somewhat worrisome. Ultimately I accepted their approach comforted that if I remained with them through the half that I could then drop away and self-manage a 7:35 pace through my hopeful P.R. finish.
°F - exacted their harsh toll. I was astounded to see just how quickly my apparently inadequate consumption of fluids and electrolytes caused me muscle cramps, a headache, lightheadedness and general weakness - which in combination forced me to a walk.
In retrospect it was fortunate that I yielded to these symptoms. During the subsequent miles walking through the remaining aid stations and slowly jogging between them I drank amply and took some extra Succeed Electrolyte Caps to restore my fluids and electrolyte deficit, and began feeling much better. Upon seeing the 3:30 pacing team pass I sped up in the final mile and ran through the finish line to the loud shouts from the crowd of tens of thousands. Though disappointed with my 3:38 time I was happy to finish healthy and to learn many lessons:
- When the predicted temperature plus dew-point is more than 120°F (Chicago's became 80°F+50°F=130°F) to back-off my target pace by at least 20 seconds per mile per 5°F above that point;
- A recent study found that marathoners slow by 19 seconds per degree over 55°F. As the average temperature was predicted to be 74°F, which translates to a six minute slow down, I should have reset my goal finishing time accordingly;
- Not to allow worries of losing the pacing team to inhibit my:
- Obligation to fully satiate my thirst (in retrospect I should have drunk three versus two cups though most of the aid stations);
- Consuming electrolytes per my prior hydration and fueling plan.
Your experience mirrors mine exactly. I started wtih the 3:45 pace group hoping to beat my PR of 3:43 and maintained this pace until mile 18 or 20. The heat got to me at the end of the race and I ended up with a 4:01. Like you I was pretty disappointed with my time, but the overall experience was great. Reading stories like yours makes me feel better about not reaching my goal. Those were indeed pretty tough conditions.ReplyDelete
Tough race, but good job rehydrating and getting back on the horse for the last bit! It was hot!ReplyDelete
Like I said before, great job, given the conditions. I had a similar experience in my marathon this year and lost a lot of time because of it. Glad you finished with no medical issues. And even though it's not close to your PR, you still ran a great time, IMO.ReplyDelete
+1, great job gutting it out. So many stories like yours at least let you know that you had tons of company. Sorry it came down to that but I know your next will be beautiful revenge, for sure!ReplyDelete
Glad to hear in the end you had a good time, I hope to run this one day!ReplyDelete
Sounds like the weather got the better of a lot of people in Chicago - great job, all things considered!ReplyDelete
Call 911, you were robbbed. No fair that you trained so hard and then got the weather that you did. What are you gonna do. Everyone imploded during that race.ReplyDelete
Thanks, all, for your support! While the weather was indeed bad I was solely responsible for my own race. My simple lesson learned - in the heat slow down, drink more and take more salt!ReplyDelete
Dave - Great job on your Chicago marathon! Your excellent performance (and that of many others) prove that weather conditions are no excuse. Weather is simply another challenge which all strong runners must learn to adapt to and overcome.
