IRONMAN™ World Championships - Kona

Big Island Triathlon

Big Island triathlon essentially revolves around Kona, the sport’s undeniable golden-child and home to the IRONMAN™ World Championships since 1981.


Compared to other areas with larger populations, however, the Kona triathlon scene is relatively small. However, you will find per capita triathlon involvement in Kona to be quite impressive. Just cruise along Alii Drive or the Queen Kaahumanu Highway anytime during the day and you will undoubtedly come across scores of triathletes in training.


And when it comes to races, the Kona-Kohala Coast is renowned globally for hosting high-quality events with devout support from the community.  Listed below are most of the Big Island triathlon and multi-sport event opportunities available for you to get involved with as either a competitor, volunteer, or spectator.

IRONMAN™ World Championships

Ironman World Championships in Kona, Hawaii

By qualification or “lottery” only. Athletes begin this iconic Big Island triathlon with a 2.4-mile swim in Kailua Bay, followed by a grueling 112-mile out & back bike ride to the northern tip of the Big Island (Hawi), and finishes with a brutally hot marathon (26.2-miles) that culminates in front of thousands of cheering spectators along Kailua-Kona’s Alii Drive. One of the best parts of the event is being able to cheer on many of your fellow neighbors who might be competing. There are also many volunteer opportunities providing behind-the-scenes insights and front-row seats to the action.
