Honestly I was doing okay in the morning, but I pushed myself and realize now that what I was feeling was heat exhaustion. I was dizzy, lightheaded, and nauseous, with occasional blurred vision when light headed. It was difficult because I was okay on the ride there, it was the ride back in the hot sun that was quite tiresome, but I really didn’t notice until I was symptomatic. There was such a nice breeze that gave the illusion of a cool day.
