Anderson Lake Backyard Ultra 2026 — Gwinn, MI

Welcome to the 2nd annual Anderson Lake Backyard Ultra. This is a 24-hour capped backyard ultra. Join us for a fun-filled day (and night) of running and camaraderie. We can’t say enough that this race is for just about everybody. This isn’t your typical ultra-marathon. We emphasize doing your best, rather than strict competition. Runners will run one 4.167-mile loop every hour, on the hour, for up to 24 hours. As long as you can make it back to basecamp and the start corral before the next hour, you’ll get to do another loop. The goal is to have fun, enjoy the company of fellow runners, and push yourself as far as you’d like. IMPORTANT UPDATE We will be shuttling all participants and spectators from the Up North Lodge Event Center parking lot during the day of the race. No parking will be available on site this year. We will have a shuttle schedule available closer to the day of the event. Basecamp Vibes ● Come prepared to get comfy! Bring fun games, tasty food, and your favorite camping chair to hang out in between loops. We’ll provide good company and a supportive atmosphere. ● No open fires are allowed at basecamp. ● If you bring pets, they must remain leashed per State of Michigan guidelines. All Abilities Welcome Forget the leaderboard. Whether you’re here to conquer one lap or gut out all 24, this is your challenge at your pace. The goal is simple: get outside, soak up the woods, and hang out with some fun folks. From seasoned ultra-vets aiming for the full 100 miles to newcomers tackling their very first lap (a breezy 5K-ish), there’s a spot for you here. Come for the adventure and stay for the vibes.

If you are not in the starting corral for the initial start, you are disqualified.

Each loop starts every hour, on the hour. 9AM, 10AM, 11AM, etc. If a runner fails to start or finish a loop within the hour, they are out of the race (Did Not Finish). ● Starting Corral: Runners must be in the designated starting corral at the bell.

If you finish your loop in 40 minutes, that’s great.

You may have as much personal aid at basecamp that you can fit in your provided 10'x10' area. Please carry enough water and calories to be able to run the entire loop, as we may not have aid stations on course this year. ● Slower runners must allow passes. ● A headlamp is required from the 7:00 PM lap onward. There is no lighting on this course, and you will be in the woods, in the dark. Failure to use a headlamp beginning with the 7:00 PM lap will disqualify runners. We strongly recommend a backup source of light as well. Winning ● One More Lap: The winner completes one final lap, alone, after the second to last runner drops out. If a runner fails to do an additional lap solo, we have no winner except in the following scenario. ● FINAL LAP: If multiple runners begin the 24th and final lap, the race is on. The first person to finish the 24th lap within the one hour time limit is our winner. All other runners who finish lap 24 within the one hour time limit are also considered finishers, you just don’t win the sweet orange Stormy Kromer as we will only have one of those for the top dog.
