Mad Backyard Ultra

The MAD Backyard Ultra is an exciting endurance running event held annually in East Ridge, TN. Participants tackle a challenging 4.1667-mile loop every hour until only one runner remains. This year marks the 4th edition of the race, which is a bronze ticket event for The Big Dog's Backyard Ultra.

Runners must complete each loop within the hour to continue, with no outside assistance allowed during the course. The last runner standing wins a unique award and a chance to enter a silver ticket event. All participants receive a commemorative coin, and those completing 100 miles earn a special belt buckle.
