I'm almost 55 and ride long distances regularly. I rode the Tour de Cure yesterday for a total of 67 miles, including a 5 mile steady climb. My actual riding time ended up at a little over 5 hours, and I can't seem to go beneath that time, which is certainly better than my first metric C three years ago. I did take it easy this week, but I also ended up nailing a BIG pothole straight on and busting a spoke (luckily my LBS did an emergency fix for me), which rattled my body pretty hard. I did have the intuition to stand, so I didn't take a shot to the groin. Maybe I should shed some weight, do some better training... Any ideas or suggestions?
