Leadville Trail Marathon & Heavy Half

June 17, 2023


The Leadville Trail Marathon & Heavy Half is a qualifier event for the famed Leadville Trail 100 Run.  The route runs through old mining roads and trails of Leadville, CO, that reach 13,185 feet of elevation through a historic district to reach Mosquito Pass. This is the highest trail marathon in the US; even in the summer, runners may see snow on the course. Participants sign up for a full marathon (26.2 miles) or half marathon (15.5 miles) and have phased start times based on runners’ pace. The marathon has seven well-stocked aid stations, and the heavy half has three. Runners will be well supported and fueled to finish in their desired timeframes. The race cut-off time is 3:30 pm, and the Awards Ceremony follows immediately at the Start/Finish Line at 4:00 pm.

This event is an opportunity to explore history. Leadville has six local museums, and the Museum Passport is available to share among friends and family to tour the historic attractions any time during race season, Memorial Day through Labor Day. A detailed list of dining and lodging options is available in the area. The most popular restaurant among locals and tourists is High Mountain Pies. Guests can stay at area hotels, bed & breakfast, home rentals, and campgrounds. Also, remember that the gorgeous Copper Mountain Resort is close-by and open for summer starting early June.

Each Leadville Qualifying Series race provides up to 25 slots for the Leadville Trail 100 Run, based on the total number of registered runners at each qualifier event. Twenty qualifying spots will be allocated based on the top age-group performances. Five will be drawn among runners who have finished the qualifier race within the allocated cutoff time.

The Leadville Race Series started in 1983 with just a single race through the Rocky Mountains. Produced by Life Time Events, it has expanded in the United States with multiple running and biking events. For trail running, the series includes the following summer events presented by La Sportiva; Leadville Trail 100 Run, Austin Rattler Run, Leadville Trail Marathon & Heavy Half, Silver Rush 5 Run, and Leadville Trail 10K. Due to popularity and participant demand, the challenging series also invites runners to a 3-day Leadville Trail 100 Run Camp camp. It is a long weekend of getting to know your fellow racers through intense training with expert runners but celebrating the amazing scenery of the Rocky Mountains with great food and trails. Leadville Race Series has many MTB events throughout the summer and fall for those also interested in mountain biking.
