The best description of how I felt yesterday was "totally trashed". My brother and I did 90 miles with several 5-7 mile climbs in the lower NC/SC mountains. It was pretty humid. And the temps were close to 90 when we finished. Total climbing feet was around 8000 feet. The signature climb was Caesars Head which is 7 miles long with grades 6-9%. When we got to the top we had to turn around and head back for 45 miles.
On the way out we hit speeds of 50 mph on a long steep road. Unfortunately we had to climb that long steep road in the heat of the day going back.
The last 20 miles were total survival. Even modest climbs required the puniest of gears. Bad state of dehydration and cramps. It was the first really warm day for me riding this year and there is definitely some acclimation needed. Plus I knew going into the ride I was not as well hydrated as I needed to be but I needed the time in the saddle.
But today things are better. Showered and a good night's sleep. I know I pushed myself beyond what was comfortable (both mentally and physically) and will be rewarded in later rides. My weight continues to drop. I was able to comfortably cinch up to another hole in my belt.
The downside is now I have to move all my wife's furniture to another office across town........yuck.
