Leadville Trail 100

Ultramarathon in Colorado

The Leadville Trail 100 Run (aka The Race Across The Sky or the LT100) is an ultramarathon held annually on rugged trails and dirt roads near Leadville, Colorado, through the heart of the Rocky Mountains. First run in 1983, the race course climbs and descends 15600 feet (4755 m), with elevations ranging from 9,200 to 12,620 feet (2,800–3,850 m). In most years, fewer than half the starters complete the race within the 30 hour time limit.

The course is a 50 mile (80 km) out and back dogleg run primarily on the Colorado Trail, starting at 10200 feet (3109 m). The centerpiece of the course is the climb up to Hope Pass at 12620 feet (3847 m), encountered on both the outbound trek and on the return.

In the early 1980s Colorado Ultra Club president Jim Butera had the idea of creating a 100 mile run in Colorado. When Aspen and Vail showed no interest Butera found support by Lake County Commissioner Ken Chlouber to hold the event in Leadville as a way to bring in visitors after the closing of the Climax Molybdenum Mine. Butera designed the course and the first running was held on August 27–28, 1983, with Butera serving as race director with the assistance of Chlouber and Merilee Maupin. Leadville is one of the four 100 milers in the United States that make up the "Western Slam", completing four western 100 mile (161 km) events: the Leadville 100, the Western States 100 in northern California, the Wasatch Front 100 in Utah, and the Angeles Crest 100 in southern California. Leadville is also a part of the Grand Slam of Ultrarunning (the Vermont 100, Western States 100, Leadville and the Wasatch Front 100, originally Old Dominion 100 instead of Vermont) and an optional part of the Rocky Mountain Slam (Hardrock 100 plus three of four other races in the Rocky Mountains: Leadville, the Bear 100, the Bighorn 100, or the Wasatch Front 100). Leadville is also one of the valid qualifying events for the Western States 100. Leadville was the venue for the American debut of the Tarahumara runners of Mexico. In 1992 the Tarahumara first showed up to run outside their native environs. Wilderness guide Rick Fisher and ultra runner Kitty Williams brought some of them to Leadville. However the experiment went bust. The problem, it turned out, was psychosocial, i. e. an unfamiliarity with the trail and the strange ways of the North. The Indians stood shyly at aid stations, waiting to be offered food. They held their flashlights pointed skyward, unaware that these "torches" needed to be aimed forward to illuminate the trail ahead. All five Tarahumara dropped out before the halfway point. The Tarahumara teams came back in 1993 and 1994 and won the Leadville event outright both years. In 1993, 52 year old Tarahumara runner Victoriano Churro came in first, followed by 41 year old teammate Cerrildo in second. In 1994, a five man Tarahumara team took on Ann Trason in a much publicized race in the ultrarunning community. Twenty five year old Tarahumara runner Juan Herrera won in a record time of 17:30. His mark stood for 8 years until broken by Chad Ricklefs in 2002 (17:23), then again by Paul DeWitt in 2004 and finally by current record holder Matt Carpenter's performance in 2005 (15:42). Trason finished in second place with a time of 18:06, which remains the course record for female runners.

The winner of the first race in 1983 was Skip Hamilton of Aspen, CO., in a time of 20:11:18

Matt Carpenter is the current course record holder. His time of 15 hours and 42 minutes in 2005 shattered the previous Leadville Trail 100 record. The publisher of Colorado Runner magazine, Derek Griffiths, said afterwards, “It was a perfect race for him. He finished in daylight, for crying out loud — no one has ever done that before. I think he has just raised the bar of ultra racing to a whole new level.”

Ann Trason holds the female LT100 record, 18:06:24, which she set in 1994. Trason is widely recognized as one of the greatest ultrarunners of all time, and nearly won the race outright in 1994. Charles Williams holds the record of the oldest man to ever complete the race, which he did at the age of 70 in 1999. He was featured in the August 1999 issue of GQ magazine, which compared his training for the race to that of a professional football player. Bill Finkbeiner became the first person ever to receive the "Leadville 2000 Mile Buckle" for twenty LT100 finishes in 2003. Finkbeiner has a total of 30 consecutive finishes, starting in 1984. In 2014, Kirk Apt finished his 20th Leadville 100. In 2019, Eric Pence finished his 25th Leadville 100, becoming the third person to earn 25 or more buckles, along with Finkbeiner and Garry Curry.
