Rasselbock Backyard Ultra (Spring)

We’ll be back in the forest next Springtime for the second edition of the Rasselbock Backyard Ultra.

The premise is simple: the event has no fixed length in time or distance, you just have to run the same 4.19-mile loop every hour and you run until you can’t run anymore. The winner is found when they are the last runner standing. The event may last 10 hours or it may last 80 hours, you just never know what will happen in a Back Yard Ultra.
