5.65 miles in 58:55 @ 10:25 pace and 171/188 for 819 calories

Assuming our baby doesn’t come three weeks early, next weekend I am racing the Take on the Heat triathlon in The Colony, benefitting The Colony Firefighter’s Association. It’s a Sprint triathlon with a pool swim that starts at 7:00am, which means that depending on how many athletes are racing day, I may not start my run until 8:20am.  Keeping that in mind, I decided to try an 8:00am to 9:00am run today and push myself to see how it felt.

It did not feel good. It was hot, over 90 degrees and not a cloud in the sky. The sun was high enough that I wasn’t able to run in the shade much, and the humidity kept the breeze from cooling me off.  I set a goal to try and maintain a 10-minute pace, and over halfway through the run I had managed to do it, even with a big hill climb at the start. But the heat got to me eventually, and pretty soon I found that I had to significantly drop my pace to keep my heart rate down.  By the time I got back to Parker Road and the final stretch to my house, I was exhausted.  I still managed to maintain a 10-minute pace during the last ten minutes, but that middle slow stretch was enough to drop my pace to 10:25.

The run was still a great test of how it might feel to really push during the heat of the race. And of course the Sprint-distance run will be 30 minutes shorter, and I won’t have to keep my heart rate artificially down.  So we’ll see how I do…
