Good job with your races Lime & KG!
It was so hot today I actually thought about putting up an accountability post here earlier, and didn't even want to do that
But when I got a call asking me to sub for an aerobics class tomorrow I knew I had to run today. I hadn't had a real workout in a week - airplanes, aerobics, the heat, getting another tooth capped, and an all-day kayaking clinic ate up all my energy this week. I'd been ready to blow off running today and hope that I'd be better acclimated to the heat tomorrow... but with having to teach again tomorrow I knew I'd better get that run today.
So I waited until at least the sun was low - the thermometer temperature doesn't really start to drop much until after sunset, but it feels a lot cooler without direct sun on my skin - hydrated profusely, and reminded myself that my tendons, ligaments and fascia would be ever so much happier running in this weather than they were when it was chilly. I told myself I'd try to keep my HR under 170. Okay, 175. Okay, 180. Will you settle for 182?
Once I was on the other side of the hills, I had to get back, right? 
4.35 miles, my usual out-and-back from home, at a pretty slow pace. Was on the edge of getting cold chills like I do when I'm overheated, but managed to avoid them. The dogs who live on my road were too hot to do much but bark halfheartedly, and the cattle didn't even have the energy to get spooked.
And now I'm over it
