Ironman Arizona

The inaugural IRONMAN Arizona was held on April 9, 2005, in cooperation with the City of Tempe and the Salt River Pima Maricopa Indian Community. With its fast course around Tempe Beach Park and Tempe Town Lake, and spectator-friendly atmosphere, the race quickly gained popularity. Given the desert heat, the race was moved to a much cooler November race date in 2008, where it attracts a wide range of triathletes who've had the whole summer to train.

Ironman World Championship

For over three decades the IRONMAN World Championship has brought the world's best athletes together in competition.
The inaugural KONA™ race was conceptualized in 1978 as a way to challenge athletes who had seen success at endurance swim, cycling, and running events. Honolulu-based Navy couple Judy and John Collins proposed combining the three toughest endurance races in Hawai’i—the 2.4-mile Waikiki Roughwater Swim, 112 miles of the Around-O’ahu Bike Race and the 26.2-mile Honolulu Marathon—into one event.
