About the race

PHASE ONE//THE LAST ONE is an endurance event in Spokane, WA, organized by Phase One Missions and staged at the Phase One training grounds including areas near Seven Mile, Riverside State Park, and Mt Spokane State Park. The format requires runners to complete a 4 miles route every hour on the hour; the event continues until a single participant remains. A runner's challenge ends if they do not complete the 4 miles before the next hour begins or if they voluntarily stop and inform the Race Director. No pacers are allowed.

The course is configured as two laps of a 1.56 mile loop plus an out-and-back to reach 4 miles, so participants encounter a hill three times each hour. Elevation change per 1.56 mile loop is roughly 80 feet. One semi-stocked aid station provides Tailwind Endurance Fuel, NeverSecond 30 gram carbohydrate gels, 1st Phorm protein bars and energy drinks, plus water and various snack options. Runners are encouraged to be self-sufficient in addition to what the aid station offers.

Crew access is allowed with tents in a designated section of the parking lot authorized by trail owners. Packet pick-up takes place at the race location on Friday, May 28 and Saturday, May 29. Required gear includes a head lamp, running gear, food, water, and electrolytes. Entry fee listed is USD 107.68 and the organizer currently states there are no refunds. Completing the endurance challenge earns a Phase One patch; registration includes a Phase One training tee. Visit the organization's website for the most recent information.
