Last One Standing Ultra Marathon

St. George, United States • 11 Dec 2026

Last One Standing Ultra Marathon - St. George, UT

This is a self supported ultra running event held on the asphalt trails of the Mayor's Loop, near the Virgin River and offering city viewpoints. The adult format uses a roughly six mile loop that is run on a 90 minute cycle; runners must return to the start/finish within each 90 minute period or be eliminated. The event includes 16 regular loops and a final 17th lap that is run all out to determine overall winners.

The kids division uses a 5.3 mile loop. Children may use any non motorized means of transport, and the kids loop follows the adult course except it omits the initial 0.7 mile out-and-back.

Distances:

  • 6 mile loop for the adult ultra
  • 5.3 mile loop for the kids division

Packet pickup and the event base are at Crosby Family Confluence Park. The park is made available to runners for personal campsites; campsites may not be reserved. A pavilion will have an assortment of food and drink, though participants are advised to bring their own supplies. One aid station will be located about halfway through the loop at St. James Park and will offer water, gatorade, and Gu products; the aid station will be unattended.

Key rules include no early starts, notifying staff if dropping out, no spectators in the start/finish corral, staying to the right on the public trail, and supervising children. Awards include a finisher medal after the first loop, a button for each lap, a belt buckle for completing all 17 loops, and champion prizes for overall male and female winners.
