Triathlon is an activity that combines swimming, cycling, and running in one event.

There are many variations of triathlons or multi-sport events that can be done as an individual or as part of a team. Triathlons are organised through independent event organisers, state triathlon associations and clubs.


To be a part of triathlon, you will need sports clothing and shoes, access to a bike and helmet (up to Australian standards), and goggles for swimming.

If you like the sport, you may want to look at using a wetsuit during the swim and perhaps, more triathlon specific clothing (though this is not essential).

Seasons / typical registration periods

Membership to Triathlon Australia is currently based on the financial year as training and activities occur within clubs all year around.

The triathlon season runs from approximately November to April each year. Check with your local club for further activity details.
