Hottest yet for me. Temp is 104 and according to the local weather center (WRAL.COM) the heat index is 118 as I type (been home about 15 mins). I can do this for about an hour, but if I had another 15 minutes to go I think I would have had to make a cooling stop. I have a few big hills as well.

I did make pretty good time, so went a more direct route that took about a mile off my reguar route. 15.50 mi in an 1:03:06 moving - thankfully only about another 4 minutes not moving.
