Last One Standing Ultra

The City of St. George's Last One Standing Ultra starts at 3 p.m. on Friday, December 11, 2026, at Crosby Family Confluence Park, 2099 S Convention Center Drive, and runs overnight into Saturday, December 12. Runners complete a 6-mile loop on the paved Mayor's Loop trail along the Virgin River every 90 minutes; anyone who misses the cutoff is out. There are 16 regular loops and a 17th all-out final lap, for 102 miles in all. New this year are two- and four-person relays, and a kids division runs a 5.3-mile loop by foot or any non-motorized wheels. Packet pickup and campsite setup start at 1 p.m. Adult entry is $90 through December 3 and $100 through December 10; relays are $180 or $360 and kids $15.
