Colorado 24 Hour Run

The event is hosted at the Swift Ponds campus of Colorado Youth Outdoors in Fort Collins, Colorado. It is staged on a flat, certified 1.0002 mile dirt loop around the ponds at an elevation of about 4,826 feet. The course is U.S.A.T.F. certified and sanctioned.

Available race durations and formats:

  • 24 Hour individual
  • 12 Hour individual
  • 6 Hour individual
  • 24 Hour relay team, teams of 2 to 6
  • 12 Hour relay team, teams of 2 to 6
  • 6 Hour relay team, teams of 2 to 6

The event uses full-lap timing: only completed laps counted on the timing mat are added to a runner or team total. Relay teams use a single bib and only laps recorded for the bib holder contribute to the team total. Runners reverse direction on the loop every six hours; reversal notices are posted at the start/finish area and runners must complete the loop they are on before changing direction.

A full-service aid station at the start/finish pavilion serves each lap with hot and cold options plus vegetarian, vegan, and gluten free choices. Richardson Hall lodge is available as a heated indoor space about 0.2 miles off the loop for runners and crews. Personal aid stations are allowed in a designated area with a recommended maximum footprint of 10'x10'. The event has a registration cap of 300.
