Birdy's Backyard Ultra, Lake Towerrinning
Birdy's Backyard Ultra is a backyard ultra event held at Lake Towerrinning, Moodiarrup, Western Australia, on Friday 7 August 2026. The format requires participants to complete a 6.71 km loop every hour, starting each lap at the same finish line, and continue until one runner remains.
The event takes place in an exclusive, locked-away venue where the caravan park and campground are dedicated to the event. The site offers lakeside camping and accommodates both runners and their supporters; the event commonly brings together about 200 runners and 400 supporters over several days.
Birdy's is affiliated with the Ultra Series and has been associated with Australian records and award-winning documentaries. Race information for this event covers entry fees, the course, aid station details, mandatory gear and related race documents. The setting concentrates runners, crews, volunteers and supporters around the loop so that laps, support and race operations happen in a single shared campground environment.
