For everyone

Whichever start line you are on.

When and where

Saturday 12 September 2026, based in and out of the Dwellingup football oval in the heart of town. Every distance starts and finishes there.

DBCA park fee

Everyone aged 17 and over on event day pays the mandatory $7 DBCA park fee. It is already included in your entry price, and under-17s get an automatic discount at checkout.

Get the app

Eventcheck IO is the official app for the weekend. Install it before event day and switch tracking on so friends, family and event staff can follow you. Coverage around Dwellingup is patchy in places, and some features need network to work.

Doing both?

If you have entered a Double, allow time to get back for your afternoon start.
