Backyard Ultra - Las Cruces

The 2025 Backyard Ultra, titled "Day of the Dead Land of Enchantment," is a unique endurance running event held at the Prehistoric Trackways National Monument in Las Cruces, New Mexico. This "last runner standing" race features a 4.167-mile loop on well-maintained crushed gravel trails with some elevation changes and scenic views of the Organ Mountain range. Starting every hour on the hour, runners must complete each loop within an hour, continuing until only one remains.

The event offers a large area for personal aid setups, campsites, and parking, with a fully stocked aid station providing hydration and snacks. Participants receive a hoodie, a Day of the Dead DNF medal, and awards for top finishers. Visit the organization's website for the most recent information.
