Last One Standing Ultra Marathon

Last One Standing 10K+ Ultra Marathon

The Last One Standing 10K+ Ultra Marathon is scheduled for December 11, 2026 in Saint George, UT. The event uses the asphalt trails of the Mayor's Loop near the Virgin River and offers views of the city. The listed venue is Crosby Family Confluence Park at 2099 S Convention Center Dr.

The race is a self-supported, loop-based ultra. The adult loop measures six miles and is repeated on a set interval; runners must complete each loop within the allotted interval to remain in the race. After 16 regular loops, a final 17th lap determines the overall winners. Runners may therefore cover distances from a single loop up to 102 miles.

A kids division follows a 5.3-mile loop that omits the first 0.7-mile out-and-back of the adult loop. Children may use non-motorized means of transport on the kids loop, such as bicycles, scooters, or roller blades.

Race logistics note that packet pickup is handled at Crosby Family Confluence Park and the park is available for personal campsites on race day; campsites may not be reserved. One aid station is located roughly halfway on the loop at St. James Park and will offer water, sports drink, and energy gels but will be unattended. Event rules include no early starts, removal of bibs upon elimination, no spectators in the start/finish corral, and an expectation that participants be courteous to other trail users.
