IRONMAN Cairns
Cairns runs both distances on the same weekend, full and half, which makes it a practical target if you are travelling a long way with a partner or a club racing different events.
The full is 3.8 km at Palm Cove, 180 km along the Captain Cook Highway between the rainforest and the Coral Sea, and 42.2 km on the Cairns Esplanade. The half covers 1,900 m, 90 km and 21.1 km on the same coastline.
June is dry season in tropical Queensland, which is the whole reason the race sits here: warm days, low humidity by local standards, and settled weather. It also falls outside the main marine stinger months, so the ocean swim is a swim rather than a risk assessment.
The highway is spectacular and unsheltered. Wind off the sea is common, the Esplanade run offers limited shade, and the heat still deserves a conservative bike even in the cooler season.
