A middle distance triathlon covers 1.9 km of swimming, 90 km on the bike and a 21.1 km run — a serious day out that rewards structured preparation without demanding the full commitment of a long course event. Oceania has a strong calendar of these races, spread across Australia and New Zealand, with events held in cities including Port Macquarie, Gold Coast, Mooloolaba, Geelong, Penrith, Canberra, Busselton and Taupo, as well as the scenic surrounds of Wānaka and St Kilda. Races run across a broad window from September through to June, with particular clusters in the southern hemisphere spring and autumn months. Organisers include IRONMAN, Challenge and T100, so the full picture has historically been spread across multiple separate websites. This page brings every middle distance race in Oceania together in one place, making it straightforward to compare dates and locations before you commit.
