Last One Standing Ultra Marathon

Event overview

The Last One Standing Ultra takes place in St. George, Utah on December 12-13, 2025. The course uses asphalt trails of the Mayor's Loop, running close to the Virgin River and offering views of the city. Packet pickup and the main race area are at Crosby Family Confluence Park, 2099 S Convention Center Dr. The park is available for runners to set up personal campsites on race day; campsites may not be reserved.

Race format and logistics

The event is a self-supported ultra with a timed loop format. The adult race is based on a 6-mile loop. Runners must complete each loop within the allotted 90 minutes to continue; failure to do so results in elimination. There are 16 regular loops and a 17th final lap to determine overall winners. A kids division uses a 5.3-mile loop, which is the adult loop minus the first 0.7-mile out-and-back; children may use non-motorized transport such as bikes or scooters.

Aid is provided at one station roughly halfway through the loop at St. James Park; supplies include water, Gatorade, and Gu products, and the station will be unattended. Awards include a finisher medal after the first on-time loop, a button after each lap, a belt buckle for completing all 17 loops (102 miles), and a champion's belt plus a gift basket for overall male and female winners. Adult entry fees are listed as $90 and $100 tiers; kids entry is $15. Visit the organization's website for the most recent information.
