IRONMAN Chattanooga“We are incredibly excited that our community was chosen to host the 2017 IRONMAN 70.3 Championships. Chattanooga is now the IRONMAN Capital of the Planet,” said Bob Doak, president and chief executive officer for the Chattanooga Convention and Visitors Bureau. “This two-day event will leave an estimated economic impact of $20 million in our community. That’s impressive. We would not have been able to do this without the existing strong partnership with IRONMAN and the dedication and support of the entire community.”

Why Hosting this Championship is Significant for Chattanooga:

  • Chattanooga is 1 of 5 cities in North America to host both a full-distance IRONMAN and a 70.3 IRONMAN
  • Chattanooga is 1 of 10 cities in the world to host both a full-distance IRONMAN and a 70.3 IRONMAN

Chattanooga beat out two other venues where IRONMAN races are held in Lake Placid, New York and St. George, Utah.

Doak added, "We have now joined the ranks of world cities to host this international event. In 2014 it was held in Mont-Tremblant, Quebec, Canada; this year, it was held in Zell am See, Austria; in 2016, Mooloolaba, Queensland, Australia; and then in 2017, Chattanooga, Tenn. The first time the United States will be eligible to host this event again will be in 2025. This is truly a once-in-a-lifetime opportunity.”
