The Back 40 Trail Run & Ride

40 mile - 20 mile - 13 mile - 5k



Run, ride, or if you dare — do both on back to back days. 


The Back 40 Run & Ride is always held on the second weekend in December. Come experience one of the newest trail systems in northwest Arkansas, opened in 2016 and nationally known. The Back 40 Trails in Bella Vista, Arkansas feature nearly 40 miles of pure Arkansas singletrack. Dirt, rocks, roots, ravines, bridges, waterfalls – we have it all. This two-day event, brought to you by the organizers of the award-winning War Eagle Trail Festival and the City of Bella Vista, brings trail runners and mountain bikers together to race through the woods. Push some limits, and have a blast doing it. 

Here in Bella Vista, we have deep woods, generous climbs and stunning views. We took advantage of this topography when Mayor Peter Christie said to build some trails! These trails meander through the woods, splash through streams, hug bluff lines and cross specially built breathtaking bridges. You’re going to want to stop for a selfie. And then, when you finish, take one with Mayor Christie, who waits at the finish!

Choose to run and/or ride from three distances – 13, 20 or 40 miles. Trail runners start the weekend on Saturday, then mountain bikers head out Sunday. Mix and match distances or go for glory by competing in the 20/20 or 40/40 option. We’ve also added a friendly 5k distance this year, for those who want a little taste of trail running.

Participants will get a shirt with the phenomenal race logo, designed by local artist and runner Ryan Holler. Finishers medals will be awarded to 13, 20 and 40 mile participants. Those brave enough to double up and tackle the 20/20 or 40/40 mile distances will get a special handcrafted award. Overall top finishers (male and female) in the 13, 20 and 40 mile events will receive podium awards as well.



  • The event is headquartered at Blowing Springs Park, and both the running and riding events will start at the Blowing Springs Trailhead. The park is located at 948 Blowing Springs Rd. in Bella Vista, AR 72714.
