David Teirney

About

David Teirney is an American ultrarunner based in Colorado who competes in trail and mountain ultra events across one of the country's most competitive and demanding high-altitude racing environments. His most prominent competitive result is a victory at the North Fork 50 Mile — a challenging 50-mile trail race in the Colorado foothills that tests runners on technical mountain terrain — and he has completed the Leadville Trail 100 Mile, the storied 100-mile race through the Colorado Rockies contested at elevations between 9,200 and 12,600 feet that is widely regarded as one of the most demanding and historically significant 100-mile events in North America. Colorado's ultra racing calendar is among the most competitive in the United States, with the combination of high altitude, rugged mountain terrain, and a deep pool of experienced local athletes providing a challenging context for any result. Teirney has built a consistent presence on that circuit, competing at events that attract some of the strongest trail and mountain runners in the country.
