Back 40 Trail Races

A One-Year Adventure at Run the Den

For 2026, the Back 40 Trail Races are taking a one-year detour!

Due to a scheduling conflict at the Back 40 Trail System, we're excited to host the first ever Run the Den Trail Races at beautiful Devil's Den State Park instead. While the location is changing, you can still expect the same high-quality Rush Running race experience that's welcoming to both first-time trail runners and seasoned trail veterans.

From top-notch course marking and aid stations to a fun, encouraging atmosphere, everything you've come to expect is coming with us to the Den.
