# Leadville Trail 100

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 15,744 feet (4,799 m). 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 run primarily on the Colorado Trail, starting at 10,200 feet (3,100 m). The centerpiece of the course is the climb up to Hope Pass at 12,532 feet (3,820 m), encountered on both the outbound trek and on the return.

## History and records

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.
In 2001, the race organizers created the Leadville Trail 100 Legacy, a nonprofit organization dedicated to promoting welfare of Lake County residents. In 2010, Chlouber sold the Leadville Trail organization and its associated events to Life Time Fitness.
Leadville is one of the four 100-milers in the United States that make up the "Western Slam", completing four western 100-mile (160 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. Unlike many other 100-mile races, Leadville has no qualifying standards. Entrance can be gained through an open lottery, via select qualifying races, through charitable donations, by signing up for coaching and/or the Leadville Run camp, or as a member of Life Time Fitness.
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, then again by Matt Carpenter in 2005, and finally by David Roche in 2024.

### Notable finishers

The winner of the first race in 1983 was Skip Hamilton of Aspen, CO., in a time of 20:11:18
David Roche is the current course record holder for the Leadville Trail 100 Race. His time of 15 hours, 26 minutes, and 34 seconds in 2024 shattered the 19 year record previously held by Matt Carpenter.
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 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.

## Leadville Race Series

The LT100 is one of six races presented under the Leadville Trail 100 banner. The other five events are as follows:
* Leadville 10K Run: This is an open event the week before the main Trail 100 race, comprising the first and last portions of the full Trail 100 course.
* Leadville Trail 100 MTB: This mountain bike race was added in 1994. The race was the idea of Tony Post, then a marketing vice president at the Rockport Company, sponsor of the event who arranged for television coverage for both races. The first mountain bike race drew just 150 entrants, while the 2009 edition allowed 1400 entrants. This USA Cycling-sanctioned race is held on a course that roughly parallels the LT100 run course, with some sections in common. It is held the same weekend as the 10K, and has attracted cyclists including Dave Wiens, Lance Armstrong and Floyd Landis. In 2010, Levi Leipheimer won the Leadville Trail 100 MTB in a then record time of 6:16:37, breaking the previous course record of 6:28:50 set in 2009 by Armstrong. The current course record is 5:58:35, set in 2015 by Alban Lakata. Howard Grotts, of Durango CO., has won the last three editions of the race, most notably in 2019 when a number of world tour road professionals competed in the race.
* Silver Rush 50 MTB: This race is a USAC-sanctioned 50-mile (80 km) mountain bike race through the mining districts east of Leadville in late July.
* Silver Rush 50 Run: This is a 50-mile trail run introduced in 2008 that follows the same route as the MTB course. The event occurs the day after the MTB event. Competitors who complete both Silver Rush events are recognized with a Silver Queen or Silver King award.
* Leadville Trail Marathon: This is a 26.2-mile (42.2 km) marathon through the mining districts east of Leadville, is held in June each year. The midpoint of the course is at Mosquito Pass, with an altitude of 13,185 feet (4,019 m). In 2006, a "heavy" half marathon event of 15 miles was added, which is run on the same day and also goes to the top of Mosquito Pass.
A competitor who officially finishes the Trail 100 Run, Trail 100 MTB, the Marathon, the Silver Rush bike or run, and the 10K is called a "Leadman" or "Leadwoman", a title which nods to the Ironman Triathlon. Charles Bybee currently holds the most Leadman titles, with 10 years of finishing all events (2007-2010, 2012–2017). In 2015, Junko Kazukawa completed the Grand Slam of Ultrarunning and the Leadwoman series, becoming the first person to complete both events in a single year. In 2019 Dion Leonard became the first male to complete the Grand Slam of Ultrarunning and the Leadman series in one year.
All events of the 2020 edition of the race series were cancelled due to the coronavirus pandemic, with all registrants given a deferral and a refund option for each race.
