Sydney's Backyard Ultra

Saint Ives, Australia • 18 Apr 2026

Event overview

Sydney's Backyard Ultra is scheduled for 18 April 2026 at St Ives Showground in Australia. The event is organised by 180 Cadence, has a capacity of 500 runners, and the entry price listed is $275.75. Race entries include an event shirt, race photos, a finishers medal, and live streaming of the event.

Format and course

The race uses the Backyard Ultra format. Runners complete a repeating loop of about 6.71 km each hour. Each loop must be finished within the hour; failing to finish or to start a loop results in elimination. The race continues until one runner remains. The course is marked the day before, has 34 metres of elevation gain per loop, and offers good visibility for supporters near the starting area.

Gear, support and rules

Mandatory items include an allocated race number, a head torch with spare batteries, a charged mobile phone (it need not be carried while running but must be available), and a reusable cup or flask because the event is cupless. Support crews may assist runners only after a loop is completed, must not obstruct runners, and must follow race official directions. Pacers are not permitted. Toilets are available; crews must take their rubbish with them. Visit the organization's website for the most recent information.
