"This is it, the race of all races. One hundred miles across the high-altitude, extreme terrain of the Colorado Rockies, this event was created for only the most determined athletes. Starting at 10,152 feet and climbing to 12,424 feet, you’ll be challenged to catch your breath — while the views try to take it away." -- Leadville Race Series
The Leadville Trail 100 MTB is one of the oldest of a growing number of 100-mile (160 km) marathon mountain bike races. It was first run in 1994 and has become one of the best known marathon events in mountain bike racing. Entry is by lottery, with entries due by the end of January each year for the race that is run the second Saturday in August.
The race is run on a 50-mile (80 km) out and back course, starting and finishing in downtown Leadville, Colorado at 10,200 ft (3,100 m) elevation. Major climbs include an over 3,000 feet (910 m) ascent from miles 40-50 to the Columbine mine, Powerline at mile 80, and St Kevins at mile 86. Total elevation gain is somewhere around 11,000 feet (3,400 m) when verified by GPS tracks of past competitors.
