I had a great time riding today in eastern MA. It's 95, but the humidity is way down from a few days ago, so it's much more comfortable.
I've found the more I bike in hot weather (most of this summer!), the more my tolerance for the heat goes up. It used to be that I thought 80 was sweltering; now I'm saying that 95 is comfortable
I couldn't do it last week, though. Tried to ride when it was 101 and really humid. I only made it 4 miles and drank half my water bottle!
