AS the temps go up here in Florida, it will be 85 by 10am and nearlng 90 by noon. I ride early, but I find that taking a cold drink for the second half of the ride is very important. I usually freeze water the night before and it thaws out as I ride. We don't have many climbs so wind is an occasion to train for climbs by heading into the wind as much as you want. Drinking water all the time during the hot season is important to rehydrating after a good ride you can't drink enough on the ride.
