Join us this spring at Devils Den State Park, an Arkansas icon nestled in the Lee Creek Valley, for the Styx & Stones Trail Races. Each of the three race distances will explore the beautiful new Monument Trail system, Devils Den’s unique rock formations and rock gardens, and given the time of year…you may experience running under a seasonal waterfall! The longer the distance, the greater the rewards including creek crossings, big climbs, and more remote technical running. 

From its inception with Mark Den Herder as RD, Styx & Stones has been about celebrating the trail community and giving back; donating 100% of any race proceeds to support the West Fork XC team. In 2022 and beyond, we will continue to honor and expand that tradition. With the help of our sponsors, our goal is that 100% of ALL race entries are donated to support local XC teamsFriends of Devils Den, and The Spark Foundation that does tremendous work in NW Arkansas providing increased access to health & fitness education and opportunities to school age children.
