The First Slaughter Pen 10K
By Lisa Mullis for ArkansasOutside.com From September 2014.
For six years, Bentonville’s Slaughter Pen Trail System hosted the Slaughter Pen Jam Mountain Bike Festival. In 2014, the event evolved beyond its cycling roots as the City of Bentonville and several community partners expanded the festival into a celebration of outdoor recreation for everyone. One of the most notable additions was the inaugural Slaughter Pen 10K Trail Run.

Before sunrise on race morning, headlights filled the parking areas near the Bark Park as runners warmed up along the Razorback Greenway. Some jogged the extra distance to the start, while others caught rides in golf carts. A light rain and cool temperatures set the stage for a memorable day on the trails.
Among the crowd were familiar faces from the Arkansas trail running community, including participants from the War Eagle Trail Twister races. Sponsored by Bentonville Parks and Recreation, the new 10K followed much of the same challenging course used by the junior mountain bike races. The route covered approximately six miles of the nine mile Slaughter Pen loop that adult mountain bikers rode one, two, or three times depending on their race category. A total of 128 runners lined up for the inaugural event.

Into the Singletrack
The race began with a short open stretch, allowing runners to settle into their pace before entering the singletrack. From there, the course quickly climbed Medusa, testing runners almost immediately with a steep ascent to the top of the ridge. Some attacked the climb aggressively, while others wisely conserved energy for the miles ahead.

Once on the ridge, runners were rewarded with flowing sections of trail that wound through rocky terrain, offering views of competitors both above and below them as the course zigzagged across the hillside. Although the overall elevation trended downhill, the route featured numerous short, steep climbs, loose descents, ravines, and technical rock gardens that demanded constant attention.
The course eventually descended onto Lower Armadillo and Armadillo’s Last Stand before transitioning onto the smoother New Creek Trail and Seed Tick Shuffle. After crossing the Razorback Greenway, runners entered the Urban Trail where rocky footing once again required careful navigation. Fatigue was beginning to set in, making every misplaced step a potential stumble.
The Final Climb
The final challenge awaited just before the finish. A short but brutally steep grassy hill forced runners into survival mode as they leaned forward and powered toward the top. Once over the crest, the course offered a welcome downhill run to the finish line, where music, cheering spectators, and fellow competitors greeted each finisher.

Although I crossed the line a few minutes slower than my goal time, I was thrilled with the experience. Every finisher received a substantial Slaughter Pen 10K medal, a fitting reward for conquering one of Arkansas’ newest trail races.

At the time, organizers hoped the race would become a permanent part of Slaughter Pen Jam and continue attracting more runners each year. While the festival itself is now part of Arkansas outdoor recreation history, it represented an important moment in Bentonville’s evolution into a destination that embraces more than just mountain biking. Events like this helped demonstrate that world-class trail systems could serve runners, hikers, families, and cyclists alike, laying the foundation for the outdoor community that continues to thrive today.
