The Leadville 100 has long been one of the country’s most iconic trail running races. It starts in the historic mining town of Leadville, Colo., and sends runners on a high-altitude voyage to the ghost town settlement of Winfield and back. Along the way, runners loop around Turquoise Lake, run in the shadows of several of the state’s highest peaks and along idyllic singletrack sections of the Colorado Trail. The biggest obstacle on the course is 12,600-foot Hope Pass, a massive climb and descent runners encounter twice between miles 40-60. This year’s race was won by Rob Krar of Flagstaff, Ariz., in 16 hours, 9 minutes and 31 seconds, while Emma Roca of Spain won the women’s race in 19:38:04.
