I was just pooped from a lot of short, very steep hills, plus a couple long climbs. I normally cruise 18-20, but I had to keep it down to 15 or I'd cramp major leg muscles. We're gradually working it back up after a period of being too busy to ride or work out much. Starting to train for next summer.
It's not that. I was averaging about 100 miles per week and then on our Sunday morning ride, about 15 miles in, I would flame out. We usually do 25-30 on Sunday mornings. Not much climbing either. Maybe 1,000-1,500 feet. So, it is not that. I really think it is a combo of heat and age but as I have said, I'd like to know for sure.
