J Treequinox

J Treequinox is a 12-hour ultramarathon held near downtown Joshua Tree, California, on a private 20+ acre desert property. The race features a 1-mile loop course, allowing runners to pace themselves one lap at a time while enjoying the serene high desert environment. Participants pass through a well-stocked, festive aid station each lap, with space for chairs and coolers near the course.

The event celebrates the fall equinox and offers custom finisher goods for those completing an ultra distance. After the run, a catered post-race meal by a local eatery provides a relaxed atmosphere for sharing stories and recovery. Visit the organization's website for the most recent information.
