Leadville Trail 100

The Leadville Trail 100 Ultramarathon first run in 1983, is an Ultramarathon held annually on trails and dirt roads at high altitude west and south of Leadville, Colorado, through the heart of the Rocky Mountains. The course is difficult, with runners climbing and descending 15,600 feet, with elevations ranging between 9,200-12,620 feet. Because of its difficulty, it is common for less than half the starters to complete the race ahead of its 30 hour time limit. The next edition of the LT100 is set for August 15-16, 2009 starting at 4am on the 15th.
