2 more miles in hot weather

I ran this morning and did 2 miles, using the 80:60 ratio. I didn't carry water even though it was hot. I stopped to rest briefly for a minute or so, mostly to recover from the heat. The shade temperature was in the 80s, probably in the 90s in the sun. Because I was out in the morning, there was some shade on the path. I saw quite a few people on the path, mostly cyclists.
