Montezuma's Revenge (bicycle race)

The Montezuma's Revenge was a 24-hour ultra-endurance mountain bike wilderness race held in Colorado each August from 1986 until 2006. Competitors were required to climb a 14272 ft mountain-Gray's Peak. The course varied from year to year but was always extremely demanding. The winner was determined by who covers the most distance in the 24-hour period. Current course records:
