Arbuckle 100

The Arbuckle 100 is a 10K, 20M, 40M, 100K, and 100 Mile trail run held on Crossbar Ranch nestled in the Arbuckle Wilderness located in southern Oklahoma. Featuring rocky ATV trails and dirt jeep roads. This is, in the Race Director’s opinion, the roughest terrain you will find in Oklahoma. The Crossbar Ranch website will tell you in bold letters (This Ain’t Your Grandma’s Backyard.) This is a 20-mile loop beginning and ending at the Crossbar Ranch entrance.

Surface: Rugged & rocky with some dirt ATV/jeep trails
– Course: Cross Bar Ranch Trails
– Elevation: about 2500ft of climbing and descending for each LOOP
– Location: Cross Bar Ranch Entrance
– Weather: Historically 45-71 degree weather.

There are multiple water crossings on this course. When driving to the start/finish, there is a rocky creek bed that is usually shallow that participants will drive over in their vehicles. The Race Director has a small hatchback that he has driven over it several times with and has had no problems.
