A legendary point to point through the San Gabriels where grit meets big mountain beauty
Overview
Since 1986, Angeles Crest 100 has lured runners into the rugged spine of the San Gabriel Mountains and sent them home changed. This is a true mountain hundred that keeps the classic soul of the original course while embracing the terrain, weather, and altitude that make the San Gabriels unforgettable.
From Wrightwood to Altadena, you will climb, descend, and traverse high country ridgelines, pine forests, sun-baked canyons, and historic singletrack. The views are huge, the community is passionate, and the finish line energy is electric. Crews, pacers, and volunteers turn the race into a rolling festival of endurance and stewardship. If you want a hundred with history, scenery, and a hard-earned buckle, AC100 delivers.
