Welcome to the 34th running of the Ouachita Trail 50 Endurance Run!

We are a 501(c)(3) nonprofit.  All donations and profits for this event will go to Pinnacle Mountain State Park. 

The OT50 was started by a group of early Arkansas ultra runners who came together, drew from their various ultra race experiences, and committed to putting on a quality fifty miler in Arkansas. As the oldest enduring Arkansas Ultra Running Association event, that intent lives on. The 50 mile and 50 km runs feature a picturesque climb over Pinnacle Mountain followed by an out-and-back traversing the rolling hills along the north shore of beautiful Lake Maumelle. Get ready for scenic, rocky, single-track as you tour Pinnacle Mountain State Park and the eastern part of the 222 mile Ouachita National Recreation Trail.
