Trail Running at Lake Murray State Park

The Lake Murray Endurance Run is an annual trail racing event held in late October within Lake Murray State Park, located near Ardmore, Oklahoma. The park is the state's first and largest, encompassing 12,500 acres of forested rolling hills. Participants run on a network of over 30 miles of trails featuring terrain that varies from flat and simple sections to moderately difficult areas containing rocks and roots.

The event offers several race distances to accommodate different endurance levels:

  • 100 Miles
  • 100K
  • 50K
  • 25K
  • 5 Miles

The races start and end at the Tipps Point Campground. This is a cupless event, requiring participants to carry their own hydration devices. Aid stations are positioned along the course at intervals between 4.7 and 6.7 miles, providing water, electrolytes, and various food items, though the 5 Mile distance does not have an aid station. Drop bags are permitted for the 100 Mile and 100K distances at specific locations.

Finisher awards are provided for all distances, with buckles awarded to those completing the 100 Mile and 100K events, and medals for the other distances. The 100 Mile and 100K races allow for pacers at designated points and times. On-site lodging options include a lodge, cabins, and RV sites, with specific areas designated for car and tent camping for participants.
