The ‘last person standing’ format fits nicely into the JATR suite of events, as we offer fun, low-key endurance events that allow each participant to reach their personal endurance goals. The Backyard Ultra is not a race against others – there is no person “in the lead” at any time. Rather, you are competing against yourself – to see how far you can go, one ‘yard’ (4.16667 loop) an hour. It is a simple concept that requires endurance, mental fortitude, planning, the ability to adapt when the plans don’t work, and the ability to enjoy your run ‘in the moment’. The format also enables us to continue our low-key, small event approach that has a community and family feel. Thank you for being a part of the JATR family with this event. We welcome any runner that would like to try the event and encourage serious competition to go as far as you can, and welcome volunteers to help our competitors during the days and nights of the run. The JATR Backyard Ultra is affiliated with the Backyard Ultra organization (

The last person standing format requires competitors to travel a pre-set 4.16667 course (this event has a daytime and nighttime course) within 60 minutes. A competitor “times out” if they are not able to finish a yard (loop) within 60 minutes or are not in the starting corral and does not start the next yard.
