IRONMAN Arizona
November 16, 2025
Event Summary
2025 IRONMAN Arizona kicks off on Nov. 16, with a single-loop swim in Tempe Town Lake, followed by a challenging three-loop bike course through the Sonoran Desert. It finishes with a spectator-friendly run around Tempe Town Lake and Papago Park.
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 have the whole summer to train.
