Australia's middle distance triathlon calendar spans the country and much of the year, with races running from September through to December and again in March, May and June. The format covers 1.9 km of swimming, 90 km on the bike and a 21.1 km run — demanding enough to require serious preparation, but accessible to athletes who are ready to commit to the training. Events take place in some of the country's most striking settings, including coastal venues such as Mooloolaba, Port Macquarie, Busselton and Cairns, as well as city-based races in Geelong, St Kilda, Penrith, Canberra and the Gold Coast. Races are organised by IRONMAN, the T100 Triathlon World Tour and Challenge Family, each with its own entry process and qualifying implications. SportsPal brings them together so you can compare dates, locations and organisers without visiting multiple websites.
