About

In 1983, 45 tough-minded runners braved 100 miles of high-altitude, extreme Rocky Mountain terrain — starting at 10,200 feet, climbing to 12,500 feet and running into global endurance history. Today, the Life Time Leadville Trail 100 RUN presented by La Sportiva is one of the oldest, most storied endurance running events in the world — with not one, but two climbs on the crux of the course: Hope Pass (12,500 feet). Every year, a select handful of gritty, gutsy and determined runners make the pilgrimage to Cloud City to Race Across the Sky and take their shot at etching their name among the Leadville Legendary.
