The Arrowtown Backyard Ultra is scheduled to commence on 8 November 2025. Participants will compete by running a course every hour until one remaining participant is left. Any competitors unable to complete a lap within an hour or not present at the start of the subsequent lap will be classified as DNF (Did Not Finish). The event’s victor is the final participant to finish a lap after all others have ceased.
The event is located at Butler’s Green, with the course leading participants along the Arrow River Trail. The terrain consists primarily of hard-packed trail, along with some sections of winding single trail through the surrounding bushland.
Participants have the option to endure the challenge alone or form a team of 2 to 4 members. Regardless of team formation, each participant must still register and compete as an individual. In the event of a team member achieving DNF status, the remaining members continue competing, with the DNF members providing support and encouragement.
The Arrowtown Backyard Ultra is a self-supported event. Participants are responsible for providing their own necessary supplies, including seating, food, and hydration.
The event is organized by Highland Events. The race format involves completing a lap per hour until a single participant remains.
