IRONMAN Hawai`i
The 70.3 on the Big Island gives you the Kona swim without the full-distance day: 1,900 m in the clear water off Kailua-Kona, 90 km on the highway across the lava fields, and 21.1 km along the Kohala coast.
The lava is the whole story on the bike. Black rock absorbs sun all morning and radiates it back at you, so the temperature you experience out there is well above whatever the forecast says. The same stretch is famous for crosswinds that arrive without warning, push you sideways, and make deep wheels a decision rather than a default.
Early June is not the October championship heat, but it is still tropical, and the run has minimal shade.
Race it as a heat event. That means starting the bike drinking rather than waiting to feel thirsty, and accepting a run pace that would look slow anywhere else. People who ignore that on this island do not finish well.
