Last One Standing Ultra Marathon

The event is a self supported ultra running event held on the asphalt trails of the Mayor's Loop in St. George, Utah. The looped course runs close to the Virgin River and offers viewpoints of the city along an out and back style route.

The adult race is based on a repeating six mile loop that must be completed within 90 minutes to remain in the event. Runners who do not return to the start/finish within the 90 minute cutoff are eliminated. There are 16 regular loops with a final 17th lap run to determine overall winners.

A separate kids division uses a 5.3 mile loop that omits the first 0.7 mile out and back. Children may use non motorized means of transport such as bikes, scooters, roller blades, Heelys, or unicycles on the kids loop.

Packet pickup and camp setup are located at Crosby Family Confluence Park at 2099 S Convention Center Drive in St. George. One aid station will be located approximately halfway on the loop at St. James Park and will provide water, Gatorade, and Gu products; the aid station will be unattended.

Race rules note that starting early is not allowed, spectators are not permitted in the start/finish corral, the course is not closed to the public so runners should stay on the right, and runners should notify staff if they drop out. Finishers receive lap buttons and medals; completing all 17 laps earns a belt buckle and overall winners receive a champion's belt and prize basket.
