Furbutt’s 24-hour Backyard Ultra

The backyard format is based on Lazarus Lake’s Backyard runs. Runners have one hour to complete the 4.167-mile course. Runners must be in the corral at the top of the next hour ready to start the next loop, or they’re out.

In addition to being a challenging run, Furbutt's 24-hour Backyard is also a great way to experience the backyard format. This is an excellent opportunity to run your first marathon, 50K or 50-mile distance because the backyard format forces you to rest early and often, which can help you run a longer distance than you thought possible.
