About this race
We are so excited to be back for our second year!
Located in the beautiful Southwestern Chihuahuan Desert, this race takes you through the canyon south of the Living Desert Zoo & Gardens on State Park and city land. Open to runners, hikers, ruckers, and walkers, you can participate in 1 of 3 challenges: 1 hour, 4 hour, or 8 hour challenge. Participants will have their selected time frame to complete as many 2-mile trail loops (out-and-back) as possible or desired. Carlsbad Roadrunners will provide support including 2 aid stations; 1 at the half-way point, and 1 at the bottom of the hill. If you have been wanting to attempt a longer distance, or even complete an ultra, this event is for you! Bring your family and friends to support you as you complete the Ocotillo Trail Endurance Challenge.
