Garden City Backyard Ultra : Toowoomba Showgrounds
The Garden City Backyard Ultra is an ultramarathon held at the Toowoomba Showgrounds in Glenvale QLD. The race uses a backyard ultra format in which competitors must complete consecutive laps of 6.706 kilometres within each hour; the last competitor remaining on the course is declared the winner. The event is scheduled for October 3, 2026 and is timed to coincide with the Toowoomba Carnival of Flowers.
The course is formed from a mix of surfaces and features within the Showgrounds: the dirt of the Main Arena, bitumen on the criterium cycling track, grass and trail sections of the Wilderness Challenge, a rocky gully, and a partial lap around the Showgrounds lake. These varied surfaces are part of each lap and recur as runners complete successive hours.
Onsite facilities include up to 100 camp sites at the showgrounds. Early bird registration is available and closes on June 29, 2026; other entry options are offered thereafter. The event is presented alongside town activities associated with the Carnival of Flowers when public parks and gardens are highlighted across Toowoomba.
