Ironman Triathlon, Kohala Coast
Concierge.com's insider take:
Every year in October, the Kohala Coast hosts the awe-inspiring Ironman Triathlon world championship: a 2.4-mile ocean swim, followed by a 112-mile bike ride through a lava field, followed by a 26.2-mile runall executed in one day under the blazing sun. (Spectators should be aware that there isn't much sun cover on the sidelines either.) For a week before and a week after the event, the quiet coast bustles with camera crews and some of the most hard-core athletes you'll ever meet. And not just energetic twentysomethingsthere are triathletes who compete through their 60s. After the event, the whole bay-front strip of Alii Drive turns into an Ironman after-party.
