Contestants run a 4.1 mile loop every hour, all day, all night, nonstop. The Big Backyard will continue until but one man is left standing… no matter how long it takes. The Last Man Standing. The last man or woman standing is crowned the victor.
The event uses exactly the same concept as the Tennessee Big dog's Backyard Ultra
