JTreequinox

JTreequinox is a 12 hour running event held in Joshua Tree, CA on private 20 acres at 6233 Juniper Rd. The course is a winding one-mile singletrack loop located in downtown Joshua Tree and the event is limited to 50 runners.

The course record is 72 laps. An Ultra is defined as 27 laps; awards are presented to anyone who completes an Ultra and to the top male and top female overall.

An on-site aid station at the start/finish offers fresh fruit, salty snacks, and electrolytes early in the day, progressing to more substantial options later including grilled cheese, quesadillas, and hot soup. There is space for a chair and a cooler next to the course, and additional pop-up tent space may be available for shared use.

Adidas Terrex and Altra will provide shoe demos during the event. Parking is available on site but limited; organizers can reserve space for large vehicles if notified in advance. Registration closes Friday, Mar 19 at 11:59 PM PT. Visit the organization's website for the most recent information.
