Caspers Trail Races

Caspers Trail Races take place in Caspers Wilderness Park in San Juan Capistrano, Orange County. The event uses trails through coast live oak and sycamore bottoms and climbs into cactus, sage, and mountain-mahogany hillsides with views back toward the coast. The routes are a mix of singletrack and fire road and are described as well marked. The park covers about 8,000 acres.

The event offers five course distances and published route details include distance, cumulative climb, and high point for each course. Race logistics note the Old Corral Day Use Area as the event location and that bib pickup times and location are to be announced. Interactive maps and elevation profiles are available via HelloDrifter. Past editions include results and photo galleries for multiple years. The event lists support from Arc’teryx and GU Energy.
