Tortugas Mountain 24 Hour Challenge
This is a 24 hour trail race held in Las Cruces, NM on November 20, 2026. The course begins at the Arroyo Loop trailhead at the Monte Vista Parking Lot and covers a 4-mile loop around Tortugas Mountain. After the first lap the direction alternates on subsequent laps. The trail is a rocky, rolling single track with some two-track sections.
The route will be marked with orange or pink flagging with reflective tape, rock cairns, and brown BLM trail markers; flagging and reflective tape will be continuously visible in line of sight. Aid stations are located at the start/finish under the covered picnic area and at the 2-mile mark; they will offer water, Heed electrolyte drink, and minimal food. This event is cupless, so participants must bring their own bottles, bladders, or cups.
Participants record each completed lap on a registration board at the start/finish and note the time of day corresponding to the official race clock. There is no requirement to be present for the entire 24 hours to have an official finishing distance; runners may leave and return and should mark themselves away on the register when off course. The field is capped at 50 participants and registration closes on Thu, Nov 19 at 11:59 PM MT. Donations are accepted as a fundraiser for the Southern New Mexico Trail Alliance, which uses funds for trail work, trainings, event support, tools, advocacy, and outdoor recreation education.
