Event overview
The Last Cowboy Backyard is a last-person-standing backyard ultra held in O'Neill, Nebraska on November 7, 2026. Runners complete repeated out-and-back laps on the Cowboy Trail, a flat, non-technical crushed-limestone surface. Each lap is 4.17 miles and the race continues until only one runner remains. Laps start and finish at the O'Neill community center. The event has a 150-runner cap. Indoor and outdoor crew areas are provided. Finisher items include a tri-blend t-shirt and a custom wooden plaque with each runner's accumulated mileage burned on site. The overall winner receives a custom belt buckle; the last male and last female receive acrylic awards.
