Every year sees triumphant breakthroughs and agonizing breakdowns played out on the sport’s most hallowed ground. Who will etch their name in Ironman Hawaii history?

The Ironman World Championship in Kailua-Kona is anyone’s race, where athletes must answer not only to the world-best competition on the day, but also to unforgiving race conditions and an all-in pressure as suffocating as the midday humidity. Still, there are a handful of athletes we’ll be watching extra closely on October 8 to drive the race-day action. (Be sure check Triathlete.com for full race-week reporting and interviews with these athletes and others.)
