The Devils Race Track Backyard Ultra
Huntsville, United States • 11 Oct 2025
Event
The Devils Race Track Backyard Ultra is scheduled for October 11, 2025, in Huntsville, Alabama at the Wade Mountain Preserve (Spragins Hollow Trailhead, 10130 Spragins Hollow Rd NW). The event is a Backyard Ultra / Last Runner Standing format. An entry fee of $95 is listed for the Backyard Ultra event on the organizer page.
Course and format
The event uses a short road out-and-back to clear the field, then a single-track trail loop that includes the Devils Race Track and portions of the Wade Mountain and Shovelton trails. After darkness, the race moves to an out-and-back on the paved Spragins Hollow Road until daylight returns. Each loop is exactly 4.167 miles (4 miles 880 feet). A horn signals the start of each loop at the top of the hour and each loop must be completed within the hour, which equates to a required pace of about 14:24 per mile.
Rules and awards
Competitors must be in the starting corral when the horn sounds; warning whistles sound at 3, 2, and 1 minutes before each loop. Except for restrooms, competitors may not leave the course during a loop and non-competitors are not permitted on the course. No personal aid is allowed during a loop and artificial aids (for example, trekking poles) are prohibited. The winner is the last individual to complete a loop; if no runner can complete one more loop than anyone else, no winner is declared. All participants receive distance results; finishers receive a shirt and a finisher cap, and runners reaching 24 hours / 100 miles receive a buckle. Results are included on Ultrasignup.
