Angeles Crest 100

The Angeles Crest 100-Mile Endurance Run, or AC100, is an ultramarathon 100 miles (162 kilometers) long that takes place annually along trails through California's Angeles National Forest. The first event was held in 1986, and was mapped out by Del Beaudoin. Since then, the course has remained mostly consistent. The original finish line was the Rose Bowl in Pasadena through 1991. In 1992 the finish line was shifted to Johnson's Field in the Arroyo, adjacent to the Arroyo Seco. In 2008 the finish line was moved to Loma Alta Park, in Altadena. Since the early 2000's the course has been extended an extra 1 mile around Cooper Canyon due to a closure enforced by the Forest Service to save the endangered Yellow-Legged Tree Frog.
