Leadville Trail 100
The Leadville Trail 100 Run (aka The Race Across The Sky or the LT100) is an ultramarathon held annually on trails and dirt roads near Leadville, Colorado, through the heart of the Rocky Mountains. First run in 1983, runners in the race climb and descend 15,600 feet (4,800 m), with elevations ranging between 9,200–12,620 feet. In most years, fewer than half the starters complete the race within the 30-hour time limit.
Course
The course is a 50-mile (80 km) out-and-back dogleg, starting at 10,200 feet (3,100 m). The centerpiece of the course is the climb up to Hope Pass at 12,620 feet (3,850 m), encountered on both the outbound trek and on the return.
History and records
Race co-founder Kenneth Chlouber, an avid marathon runner, conceived of the race as a way to make Leadville famous and bring visitors during a period of economic downturn. When he told the local hospital administrator about his idea he was told, "You're crazy! You'll kill someone!" Chlouber responded, "Well, then we will be famous, won't we?"
