Two rides come to mind; one was during the Horrible 100 in hilly Clermont, FL. I threw the chain during one of the climbs (going up the Wall). Did that ride solo in just over 5 hours. The other one was another century ride, leaving from the Homestead racing track to Key Largo and back_ this was probably the fastest ride I've been in since we finished in 4:07. My legs were cooked for the rest of the day but felt surprisingly well the next day...
