Ultrarunners race one hundred miles through Leadville mountains
Plan a Colorado getaway for Leadville Trail 100 Run, combining 100 miles of overnight mountain ultrarunning with outdoor recreation and an overnight-friendly summer schedule.
Event details
The original Race Across the Sky sends ultrarunners on an out-and-back course over Hope Pass each August, through extreme elevation, overnight running, and dedicated pacer support across some of Colorado’s most demanding high-altitude terrain. Aid-station volunteers welcome spectators and can point families toward the best nearby vantage points along the course.
Families supporting a runner effectively become part of an overnight crew operation themselves, tracking progress through aid stations across day and night rather than watching from a single fixed spot, a genuinely immersive way to experience the race even without running a step of it.
The overnight race, crew logistics, and altitude acclimation generate several nights of lodging demand around Leadville. Reserve a Stay well in advance given the event’s prestige, pack layers for both daytime heat and genuinely cold mountain nights, and frame the trip around Twin Lakes or Turquoise Lake between aid-station stops. It is ultrarunning’s most storied hundred-mile test, best supported by families ready for a long day and night themselves. Cell service is unreliable across much of the route, so agree on fixed meeting times and places with any runner in advance.
