How do you ride? Two answers and the physics runs over this exact course.
Pick a ride level and your predicted finish for Leadville Trail 100 MTBappears here — computed from the course's real elevation, surface, and aid stations.
This is it. The Race of All Races. In 1994, 150 gutsy riders braved 100 miles of high-altitude, extreme Rocky Mountain terrain — starting at 10,152 feet, climbing to 12,424 feet and pedaling into global cycling history. Today, the Life Time Leadville Trail 100 MTB is one of the most prestigious endurance cross-country MTB events in the world. Every year, a select handful of gritty and determined cyclists make the pilgrimage to Cloud City to Race Across the Sky and take their shot at etching their name among the Leadville Legendary. The red carpet awaits.
