Drove to Arrowhead Lakes to start ride with Paul F. It was windy about 20 mph, out of N - NE. Temps were nice at start yet I got a bit heated near the end and needed to take a break at Rio Vista park at mile 57. Turns out I drank 1 full bottle of water there and refilled and in the last 6 miles, drank that bottle. Overall I drank 4 bottles of water. Compare that to a couple days ago when I drank less then 1 bottle. We started strong and had a wonderful return ride from the turn around in Vistancia. We stopped at the Litchfield Park plaza water & a/c restrooms. Then we headed for the slugfest of ~22 miles up to Arrowhead Lakes, into the wind. I started to feel overheated, tired, and thirsty. Paul was kind enough to keep the pace low. I also know that the night before we had supper ( home made naan pizza) at about 4:30pm, so way early. I had a light breakfast of a piece of toast with peanut butter and 1 bowl of wheat chex cereal.
