About
Test your endurance and mental toughness at The Last Cowboy Backyard, Nebraska's own backyard ultra, held in O'Neill. The format is simple and brutal: complete a 4.2-mile loop on the Cowboy Trail every hour, on the hour, until only one runner remains.
The loop starts and finishes at a community center, and to stay in the race, you must be ready in the starting corral at the top of every hour. Custom wooden plaques commemorate each runner's total mileage, and unique awards go to the overall winner and to the last man and woman standing. With the field capped at 150 runners and a welcoming atmosphere, it's a genuine test for athletes of every background looking to push their limits.
