I know a guy who took 10th in the Colorado District Championships, he'd have done better but for puking from some bad food
"Won" a double century in 9 or 10 hrs- he got tired of riding alone and took a nap until the 2nd place rider,( a cat 2 racer), caught up to him
Did a hilly 180 mile ride and then did a club ride as if he were fresh
Did the tour of Swan River in Montana more than once,(231 miles in 2 days) He had a bell mounted on his h-bars and would ring it as he passed or just to say "Hi". A tandem rider who he'd passed several times was overheard to say. "If he rings that damned bell one more timeI'm gonna shove id up his a**) good luck finishing that one pal!!
Rode 60-70 miles round trip to go xc skiing apx 4500 ft up a mtn to get to the "track", lots of snow that year and as I recall it was really cold, Yes he ahd studded tires
and more, ad nauseum
All on a Schwminn Spitfire fat-tired cruiser with 52X18 gearing!!
