To put the Mont Ventoux climb in perspective, in English units that's about 6000 feet of climbing in 13 miles. That is a long steep climb. The biggest "short distance" climb that I did in a race was the Santa Fe Hillclimb Race in August of 2000. Started at Fort Marcy Park (in Santa Fe NM, not where Vince Foster's body was dumped), about 7000 feet, to the Santa Fe Ski Basin, about 10300 feet, all within 15 miles. OK, so there's an altitude factor in that one. My legs were so fried at the end (not to mention the altitude headache), I rode a pickup truck back to the start instead of the bike.
