Hello all, and first, thank you for such a great forum!
I'm getting back in to cycling after about a 20 years hiatus, and oh, how I love it. Been riding now for about 2-3 months.

However, (and there's always a however), I live in Florida, and it is August. At 9:44am, the bank sign said 86 degrees. An estimate of the humidity would be about equal to the temp. I started this morning at 6:45, just at sunrise. At about mile 27, I stopped for a trail mix and stretch break. At mile 33 or so, I hit the "I can't do this anymore" wall, which was unfortunate as I still had another 7 miles to get home. I stopped into a Dunkin Donuts, got an iced coffee with cream/sugar, and got back on. The last few miles were not pretty, but I made it home - average speed only 11.7mph, which even for my slow self is sad. So with that long intro, my question for you more experienced riders is twofold:
1. How do you deal with heat and humidity without wilting in the saddle? I've seen some neck cooler cloths out there, any help? Anything you do that makes it more bearable?
2. How do you deal with hitting the wall? What gets you through?
Many thanks,
B
