Tortugas Mountain 24 Hour Challenge
The event is a 24 hour trail race held in Las Cruces, New Mexico on November 20, 2026. The course uses the Arroyo Loop trailhead at the Monte Vista Parking Lot and completes laps around Tortugas Mountain. Each lap is approximately 4 miles; the first lap proceeds clockwise and subsequent laps alternate direction.
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, with flagging and reflective tape visible in line of sight.
Aid stations are located at the start/finish under a covered picnic area and at the 2-mile mark. Aid stations will offer water, Heed electrolyte drink, and minimal food; participants should plan to provide most of their own food. This is a cupless event, so participants must bring their preferred drink vessel. Crews and supporters are allowed at the start/finish aid station.
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 remain on site for the entire 24 hours to record an official distance; participants may mark themselves away and may leave and return to run additional laps within the 24 hour period.
The entry is free as a "Fatass" race, with donations accepted to benefit the Southern New Mexico Trail Alliance. The field is capped at 50 runners. Registration closes Thu, Nov 19 at 11:59 PM MT. Visit the organization's website for the most recent information.
