Leadville Trail Marathon and Heavy Half
The Leadville Trail Marathon and Heavy Half are trail races held in Leadville, Colorado during the late June 2026 event weekend. Expo and packet pickup take place at an expo location on E. 6th and Poplar; athletes must pick up packets in person with photo ID.
The marathon is an out-and-back route that follows old mining roads and single track through the historic mining district on the east side of Leadville. The course tops out at Mosquito Pass at 13,185 feet. Snow on portions of the route is possible. Courses are marked with fluorescent pink-and-black striped ribbon and flour arrows.
There are seven aid stations on the marathon course and three on the Heavy Half. Aid stations provide water, Neversecond energy gels and high-carbohydrate beverage mix, Skratch Labs hydration, energy bars and chews, and assorted foods such as bananas, figs, pretzels, chips, and cola products. Course cutoffs include an outbound cutoff at Adelaide and inbound cutoffs at Resurrection, with a total course cutoff of 4:00pm for both events.
Additional details include minimum age limits, entry fees, crew access rules that limit crewing to the Start/Finish area and Resurrection Aid Station, required parking at community lots with shuttle service to the start area, awards categories, and LT100 qualifier coin distribution for marathon finishers.
