Last One Standing Ultra Marathon

Event overview

The Last One Standing 10K+ Ultra Marathon is a self-supported ultra running event in St. George, Utah. The course uses the asphalt trails of the Mayor's Loop near the Virgin River and offers city viewpoints. The event base is Crosby Family Confluence Park at 2099 S Convention Center Drive. Registration closes on Thu, Dec 11 at 11:59 AM MT.

Race format and rules

• 6-mile loop for the adult ultra, run on a repeating schedule with a 90-minute time limit to complete each loop.
• 5.3-mile loop for the kids division; this loop omits the first 0.7-mile out-and-back and allows non-motorized transport.

Runners who do not return to the start/finish within 90 minutes are eliminated. There are 16 regular loops and a 17th final lap to determine overall winners. The event is open to all as a self-supported format. Starting early is not allowed. Spectators are not allowed in the start/finish corral. The course is not closed to the public, so runners must stay on the right side of the trail and be courteous. Runners should notify staff if they drop out.

Logistics, aid, and awards

Packet pickup is held at Crosby Family Confluence Park. The park area is available for personal campsites on race day; campsites may not be reserved. One aid station is located roughly halfway through the loop at St. James Park and will offer water, gatorade, and Gu products; the aid station will be unattended. Finishers who complete the first loop on time receive a medal. A button is awarded after every lap. Runners who complete all 17 loops receive a belt buckle for 102-mile completion. Overall male and female winners receive a champion's belt and a prize basket. Visit the organization's website for the most recent information.
