Leadville Trail 100 MTB 2026
About This Event
One hundred miles and 12,000 feet of elevation gain at altitude reaching 12,600 feet makes this the ultimate test of mountain bike endurance. The course is a brutal out-and-back route from Leadville that drops to 9,200 feet at Twin Lakes before climbing to the infamous Columbine Mine at 12,496 feet, where the thin air and relentless grade separate the determined from the defeated.
Born in 1994 when 150 riders decided to tackle the same challenge as the legendary Leadville 100 Run but on two wheels, this event has become the gold standard of high-altitude mountain bike racing. The course mixes rough forest service roads and alpine two-tracks with technical singletrack sections that demand focus even when you’re oxygen-starved and exhausted.
Waves start at 6:30 a.m., giving you 12 hours to earn the coveted “Small Buckle” or 9 hours for the prestigious “Big Buckle.” Aid stations at Pipeline and Twin Lakes keep you fueled with the essentials, but this is largely a solo battle against the mountain and your own limits.
The lottery-based entry system reflects the event’s prestige—finishing Leadville earns you a belt buckle that carries serious respect in the mountain bike community. Veterans describe it as equal parts suffer-fest and spiritual experience, with the post-race festival from noon to 8 p.m. serving as a celebration of what participants just survived.
This isn’t just a race but a pilgrimage to mountain biking’s most hallowed ground, where completing the course within the cutoff is considered a remarkable achievement that changes how you view your own capabilities.
