Swan River Half Marathon and Fun Run 2026

HBF Run for a Reason is Perth's biggest annual fitness and fundraising challenge, uniting tens of thousands of participants every year since 2010. This iconic event invites West Aussies to run, walk, or wheel for a cause that matters to them, fostering community spirit while raising vital funds for charities close to their hearts.

With the event selling out two years in a row and 40,000 participants last year, be sure to register today so you don't miss out.

Free Membership - Volunteers are so important to ATTA, that we have introduced a Free Membership category for those people kind enough to offer their time to help at two events. Volunteers will also receive a notional payment to compensate for their time and travel costs. You can find more information about volunteering and the different roles invoved HERE.

ATTA Membership gives you a $10 discount on race entry fees to all ATTA events during the year and priority entry even when ATTA events are oversubscribed.

To encourage and support Junior cycling in WA, ATTA Membership and race entry are free for participants aged under 18.

The Committee has agreed to keep the Membership prices the same as last year

ATTA is an Association that is run by volunteers and is wholly dependent on its Members and others to volunteer their time so that our events can be run safely and in compliance with our local government and MRWA approvals. Members are expected to volunteer at events throughout the year and the awarding of trophies and prizes will be conditional upon Members having volunteered their time.
