Backyard Ultra

The backyard ultra is the fastest-growing format in endurance running (+25% annual growth). The concept is simple: run a 4.167-mile loop every hour, on the hour, until everyone else stops. Last person standing wins. There's no set distance — races have lasted over 100 hours. The format rewards consistency, mental toughness, and pacing discipline over raw speed, making it surprisingly accessible for experienced runners over 50.
