Micah True

During the 1980s and 90s True spent several months per year trail running in Central America. In 2003 True decided to organize a race for the Tarahumara people in Mexico that would help them preserve their culture and running heritage. True died on March 27, 2012, during a run in the Gila Wilderness, part of the Gila National Forest in southwestern New Mexico.

The 2012 event took place on March 12 and was the largest ever with hundreds of participants. Most were local Tarahumara, known for their running endurance, both as a general means of travel and while participating in ceremonial, team-based, long distance running events, most famously the Rarajipari, or ball game. In addition to prize money for the top ten finishers, the event awards seed corn vouchers to all runners who complete the distance. The race has its start and finish in the town square of Urique, Chihuahua, Mexico, covering an estimated 50 miles (80 km) of single track trail and dirt road.

On March 27, 2012, True failed to return after heading out for a run in the Gila Wilderness, part of the Gila National Forest in southwestern New Mexico. He departed from the Wilderness Lodge in Gila, saying he was going for a 12-mile (19 km) run. A subsequent mountain rescue effort involved three aircraft and at least nine search and rescue teams in off-road vehicles and on horseback, looking across 200,000 acres (81,000 ha) of high desert. Searchers included ultra-runners such as Scott Jurek, Kyle Skaggs, Timothy Olson, and many athletes and friends who had participated in the 51 mile Copper Canyon Ultra Marathon.

In 2009 True was featured prominently in Christopher McDougall's best selling book Born to Run. The book told the story of the Copper Canyons ultra marathon and the Tarahumara, while promoting the endurance running hypothesis, arguing that humans left the forests and moved to the savannas by developing the ability to run long distances in order to hunt prey by simply outlasting them in a long chase.

In 2006 True had the idea of inviting American ultrarunners to compete with the Tarahumara. After initially reaching out on the internet, he wrote an article in Men's Health, elucidating many of the lessons he internalized from the Tarahumara people. He also contacted Christopher McDougall, a writer for Men's Health, who would later write the book Born to Run.

In 2003 True decided to organize a race for the Tarahumara natives that would help them preserve their culture and running heritage. The first Copper Canyon Ultra Marathon was held on March 23, 2003; though turnout was small, it became an annual tradition.

In 1993 True came in contact with the Tarahumara or Rarámuri runners from Chihuahua, Mexico. In 1994 he began spending his winters running in the Copper Canyons, where he built a hut and began establishing a relationship with the Tarahumara natives.

By 1982 True had moved to Boulder, Colorado, where he began working as a self-employed furniture mover. By then he had become a "trailrunning bum" (like a "surfing bum or a climbing bum"). For almost 20 years, he spent winters running in Mexico, Guatemala, and Central America, averaging 170 miles (270 km) per week. He would return to Boulder during the summers to earn enough money to live on the rest of the year. Among villagers he became known as "El Caballo Blanco" or "The White Horse" for his long blond hair and pale skin.

True attended Humboldt State University, where he studied Eastern religions and Native American history. To earn money he began prizefighting in informal boxing bouts, using the name "Gypsy Cowboy," and perhaps taking the occasional dive for an easy payday. Between 1974 and 1982, Hickman was a professional middleweight boxer, fighting under the name Mike "True" Hickman. His career record was 9 wins (KO 2), 11 losses (KO 9), and 0 draws.

Micah True was born Michael Randall Hickman in Oakland, California, the son of a World War II Marine Corps Gunnery Sergeant and the second of four children. He grew up traveling the country as his family relocated to various nationally located Marine Corps bases. His family was conservative Roman Catholic, but True aligned himself with the counter-culture movement of the 1960s and 70s.

Micah True (November 10, 1953 – March 27, 2012), born Michael Randall Hickman and also known as Caballo Blanco (white horse), was an American ultrarunner from Boulder, Colorado, who received attention because of his depiction as a central character in Christopher McDougall's book Born to Run. True's inclusion in the book garnered him some attention in ultrarunning circles, and some readers credited him as their inspiration for taking up the sport.
