Prepare for a unique desert ultra experience at the J Treequinox, a 12-hour timed running event set for March 21, 2026, in the stunning landscape of Joshua Tree, California. This intimate race, limited to just 50 runners, offers a distinctive challenge on a 1-mile singletrack loop course. Runners will navigate rolling terrain on a private 20+ acre property, with approximately 50 feet of elevation gain per lap, all while immersed in the captivating scenery of the high desert and its iconic, Dr. Seuss-like Joshua Trees. Typical race day conditions in late March bring comfortable highs around 72°F and lows around 44°F, with a minimal 1% chance of precipitation, though desert weather can always surprise.

The J Treequinox is celebrated for its welcoming, low-key atmosphere, making it an ideal event for those looking to explore ultra-running or achieve a new distance goal. The event kicks off at 7:15 AM at 6233 Juniper Road, where the main aid station serves as the hub for all participants. Described as "well stocked, fun, and festive," this aid station is conveniently located at the start/finish, allowing runners to access support, personal coolers, chairs, or even small tents every lap.

Beyond the personal challenge of a 12-hour effort, the J Treequinox offers a rewarding experience. Finishers who complete an "ultra distance" of 27 laps receive custom awards, with accolades also given to the top male and female overall. The camaraderie continues post-race with a catered spread from local Joshua Tree eatery, The Dez, where participants can share stories and gather around a campfire, celebrating their incredible journey under the vast desert sky.
