What is the appeal of the backyard ultra?

A “backyard ultra” asks runners to complete 4.16 miles (an hour-long loop) every hour until only one participant remains. The concept began in America, created by endurance race designer Lazarus Lake, behind the acclaimed Big’s Backyard Ultra, which requires qualification. In the UK, the format has spread across multiple locations, and an event in Shropshire has now been announced for April 2027 at the West Mid Showground in Shrewsbury. Organiser interest is driven by the race’s simplicity and mental challenge rather than speed, according to first-time runner James Morgan. Sarah Perry, the women’s backyard ultra world record holder, highlights inclusivity, supported checkpoints every 4.16 miles, and the appeal of lining up against men.
