Dollars for Scholars 10K

So, the annual Dollars for Scholars 10K run was last Friday.. at 6:00 and 85 degree heat! I had high expectations, I knew I'd be making around 45ish minutes because that's what I'd been training for, and was ready to blow my time from last year (1:00:12) out of the water... unfortunately I forgot about the heat. I ended up walking. Twice. The course was a double loop, once for the 5K-ers and two for the 10K-ers. I had to walk at about 4.5 miles, and then again at 5. I was NOT happy. I didn't walk for long, just enough to catch my breath and not hyperventilate.. I almost passed out once before one summer because I got too hot... that was really scary. I had no phone on me and was about 5 miles away from home.. I never want to feel like that again. My time ended up being right at 55 minutes... at least I beat my last time I guess. Stupid heat!!!! My 1/2 marathon pace was faster than that! Grrrr.....
