Last One Standing 10K+ Ultra Marathon : St. George, UT

The event is a self-supported ultra run staged on the asphalt Mayor's Loop near the Virgin River in St. George, Utah. Runners repeat a roughly 6-mile loop that starts on the same course every 90 minutes. Competitors must return to the start/finish within 90 minutes each lap to remain in the race; failure to do so results in elimination. There are 16 regular loops followed by a final 17th lap run as an all-out finish to determine overall placings.

Packet pickup and the race base are at Crosby Family Confluence Park, 2099 S Convention Center Drive, St. George. The park is available for runners to set up personal campsites; campsites may not be reserved. One aid station is located about halfway through the loop at St. James Park; it will provide water, Gatorade, and Gu products and will be unattended.

A 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 and must be supervised. Key race rules include no starting early, notifying staff if withdrawing, and that the course is open to the public so runners should stay to the right and be courteous. Spectators are not allowed in the start/finish corral.

Awards: a finisher medal after the first on-time loop, a lap button after each lap, a belt buckle for completing all 17 loops (102 miles), and champion awards for overall male and female winners. Visit the organization's website for the most recent information.
