The Chimera takes place in the Trabuco District of the Cleveland National Forest in Southern California in what is known as the Santa Ana Mountains. Due to the Holy Fire, this year's event will take place in conjunction with the Old Goat Race and make use of the Old San Juan Trail and Chiquito Trail which connect Hot Springs Canyon with Bluejay Campground and the Candy Store. These three locations will be fully-stocked aid stations that allow crew access. Two minimally-stocked aid stations will be located at Chiquito Falls and Cocktail Rock on remote parts of the course where there is no crew access. The race will start at Lazy W Ranch where bunkhouses, electricity, hot showers, and a much easier drive in from the Orange County side all await you.
Both distances start at 5:00 AM. You have 33 hours to complete either distance. Pacers are allowed after 7 PM or after 50 miles, whichever comes first.
