About the race
Backyard Everest is a timed loop event at Black Hill Conservation Park, Athelstone, South Australia, held over a 24-hour period on 11–12 September 2027. Runners complete a 5.3 km loop that gains 369 m of elevation each lap; lap totals are used to track progress toward seven named summit milestones culminating at Mount Everest.
The event offers multiple entry durations:
- 24 hours
- 12 hours
- 6 hours
- 3 hours
Each hour a lap starts on the hour. Runners in time-limited categories receive one chip token per entered hour; handing a token to the Gatekeeper allows entry to that hour’s start. Full 24-hour entrants are committed to every lap and do not receive tokens. Laps must be finished within the hour to count; missed cutoffs do not eliminate a runner but that lap’s distance is not added to totals. Additional chip tokens may be purchased during the event; issued tokens are non-transferable and non-refundable.
Base Camp near the start provides water, electrolyte hydration, cola, crisps, lollies and fresh seasonal fruit. Runners may set up personal supplies in designated areas and should bring their own cup or hydration vessel. A headlamp is required at night. Pacers are not permitted. Entries are limited to 300; refunds are not available and transfers follow Race Manual terms. Weather averages for Adelaide in September are minimum 10ºC, maximum 19ºC, and about 50 mm rain over eight days. Visit the organization's website for the most recent information.
