Event overview

The Lake Murray Endurance Run is held annually in late October at Lake Murray State Park near Ardmore, Oklahoma. The event offers trail races at multiple distances and uses Tipps Point Campground as the start and finish area. Race shirts are provided to participants who register in time, and awards include finisher buckles for the 100-mile and 100K events and medals for the 50K, 25K, and 5-mile events. Packet pick-up and same-day registration are available before race day.

Course, support and rules

Distances offered:

  • 100 Mile
  • 100K
  • 50K
  • 25K
  • 5 Mile

The park covers 12,500 acres with over 30 miles of trail. Trail terrain varies from simple and flat to moderately difficult sections with rocks and roots. Aid stations are cupless, so runners must carry their own hydration device; water, sports drink and food items are supplied at aid stations spaced about 4.7 to 6.7 miles apart. The 5-mile event does not have an aid station.

Drop bags are allowed for the 100-mile and 100K at the Start/Finish and at the Buzzards Roost aid station. Time limits are set by distance: the 100-mile course has a 32-hour limit and the 100K has a 27-hour limit; shorter distances are expected to finish the same day. Pacers are permitted for the 100-mile and 100K at specified mile points or once it is dark, with exchanges only at Tipps Point or Buzzards Roost. Registration credit and transfer rules apply when cancelling within specified time windows. Visit the organization's website for the most recent information.
