The Last Cowboy Backyard

Step into the third annual Last Cowboy Backyard Ultra in O'Neill, Nebraska—a unique endurance challenge set along the picturesque Cowboy Trail. This flat and runnable course features 4.167-mile out-and-back loops with minimal elevation changes, making it ideal for those aiming to push their distance limits or tackle their first ultramarathon. The race begins at noon on October 23, 2027, adhering strictly to the Backyard Ultra format: complete a loop every hour until only one runner remains.
The O'Neill Community Center serves as both start/finish and crew area, offering climate-controlled indoor space with restrooms just steps away from the starting line. This setup ensures runners can comfortably refuel and prepare for each new lap regardless of weather conditions, making it an ideal venue to test your endurance in November's unpredictable Nebraska climate.
Beyond the competitive spirit, The Last Cowboy celebrates every runner’s achievement through custom swag: a race shirt and buckle marking exact mileage completed. For those who exceed 200 miles, a personalized Sheridan buckle awaits as recognition of their extraordinary feat.
Join us for an unforgettable event where you can challenge yourself in one of the most supportive environments Nebraska has to offer. Whether your goal is modest or ambitious, The Last Cowboy offers a unique blend of community and competition that will leave you with memories—and possibly new personal bests—that last far beyond October 23rd.
