Coldwater In Your Veins

Event overview

Coldwater In Your Veins is a Last Person Standing running event held at the Horse Corral at Coldwater Canyon in North Ogden, UT. The race date is May 30, 2026. Registration opens 1/1/26 and closes on May 29, 2026. The event uses a repeated lap format where runners continue until the field is reduced by the race rules.

Course and format

Each lap is a 7.7-mile loop with about 1,200 feet of vertical gain per lap. The course starts and finishes at the horse corral pavilion and is run clockwise on odd laps and counterclockwise on even laps. Runners have a fixed time limit to complete each lap; failing to return to the runners corral before the next lap start results in disqualification. Runners must carry the aid they need, and no pacers or external help are allowed except from other racers. The race requires at least two runners to start each loop for the event to continue; the winner must complete the last loop that the second-place runner does not complete.

Logistics and crew

The venue provides a pavilion, bathrooms with running water, and a 10x10 foot spot in the horse arena for a tent or canopy. Crews are allowed at the venue. Organizers provide water and electrolyte options, but teams are advised to bring specific supplies. The ground in the corral is soft and sandy, so stakes are ineffective; weights are recommended for canopies. Wind and goathead thorns have been noted in prior events.
