A good way to get heat stroke

Do this in 85 degree F sunny weather.  It's no wonder I slowed down those last two miles.

BTW, since I knew it was hot, I turned off the pace alarms and maintained a somewhat comfortable pace.  Of course, that pace became uncomfortable after a bit, and I almost shut it down after three.  But, I had brought water and was determined to get in 5 miles even if I had to walk.

I hope my body realizes it's summer and adjusts tonight...
