At 4 a.m. on Saturday, Aug. 22, 657 runners competed in the Leadville Trail 100 run in Leadville, Colo., a grueling 100-mile trail run beginning at 10,000 feet of elevation and climbing twice to 12,500. Manahawkin ultra-marathoner TJ Hoffman was one of them.

The race was founded in 1983 by Ken Cholouber, who wanted to bring awareness and tourism to the titular old mining town after the closure of the Climax Mine.
