Simply put, the nation’s toughest marathon.

The Life Time Leadville Trail Marathon and Heavy Half presented by La Sportiva takes trail runners through the historic mining district’s challenging trails to the highest point of any Leadville Race Series event: Mosquito Pass (13,185 feet).
As you take on the baddest trails and thinnest air in all of endurance racing, you’ll need all the Grit, Guts and Determination you can muster.

The Leadville Trail Marathon is 26.4 miles of out-and-back dirt roads and single track that takes you through the historic mining district on the east side of Leadville. The Heavy Half consists of 15.46 miles along the same path as the marathon minus the Ball Mountain section. The course is primarily on old mining roads and trails, topping out at 13,185 feet at Mosquito Pass. This is the HIGHEST continuous pass in the country and the highest trail Marathon in the USA! There is a chance you’ll see snow on the course. The courses will be well marked with fluorescent pink-and-black striped ribbon and flour arrows on the ground.
