Last One Standing Ultra, St. George
The Last One Standing Ultra is a self-supported multi-loop running event held December 11–12, 2026 in St. George, Utah. The course uses the asphalt trails of the Mayor's Loop, which run close to the Virgin River and provide views of the city. The event is based at Crosby Family Confluence Park.
The adult Ultra is built around a 6-mile loop that is repeated on a 90-minute cycle. Runners must return to the start/finish area within each 90-minute window to remain in the race; failure to do so results in elimination. The event features 16 regular laps followed by a 17th final lap to determine overall winners. A kids division runs a 5.3-mile loop that follows the adult course except for the first 0.7-mile out-and-back; children may use non-motorized means of transport on that loop.
Packet pickup and the event base are at Crosby Family Confluence Park. The park is available on race day for participants to set up personal campsites; campsites are not reservable. There is one aid station roughly halfway through the loop at St. James Park supplying water and Gatorade; the aid station will be unattended.
Key rules include no early starts, on-time completion of each loop to avoid elimination, notifying staff when dropping out, and no spectators in the start/finish corral. Awards include a finisher medal after the first loop, a lap button after each loop, a belt buckle for all 17 loops, and a champion's belt plus a prize basket for overall winners.
