Chattanooga will play host to the 2027 Ironman 70.3 World Championship, the pinnacle event of the middle-distance triathlon scene.
The championship will be Aug. 28-29. More than 7,000 professional and age-group triathletes are expected to attend after qualifying at one of 120 events worldwide.
Chattanooga hosted the 2017 70.3 World Championship, the first contested across two days. It had a record field of more than 4,500 athletes from 90 countries, regions and territories. The successful execution of a multi-day championship format solidified Chattanooga’s reputation as a world-class host.
“Chattanooga has welcomed Ironman participants for over a decade. It’s a key part of our sports landscape,” said Chattanooga Mayor Tim Kelly. “Ironman brings in top athletes from around the world and showcases our great city to so many. We appreciate Ironman for signing up with Chattanooga for another five-year run. This championship will be a further driver of the city’s tourism economy.”
The announcement comes as part of a new five-year agreement that reinforces Chattanooga’s role as a key destination on the global Ironman race calendar. The partnership includes the return of an Experience Oman Ironman Pro Series event to Chattanooga in the coming years.
Since first hosting an Ironman event in 2014, Chattanooga has consistently ranked among the largest and most popular races in the United States. Events draw thousands of athletes annually as a recurring stop on the professional racing calendar. The city’s course features a stunning swim in the Tennessee River, rolling bike terrain into northern Georgia, and a scenic, spectator-friendly riverwalk run described by athletes as inviting and competitive.
Scenery, Champions
Set along the Tennessee River and framed by the Appalachian foothills, Chattanooga has a decade-long history of hosting Ironman and Ironman 70.3 events. The city offers a unique combination of scenic racing, experienced event delivery and strong community support.
In 2024, Chattanooga was named the “Friendliest City in the U.S.” by Condé Nast Traveler as part of its prestigious Readers’ Choice Awards. As North America’s first National Park City, Chattanooga stands at the forefront of urban sustainability and access to the outdoors. Its breathtaking landscapes and outdoor lifestyle have earned it repeated honors from Outside Magazine as the “Best Town Ever.” A growing culinary scene has garnered acclaim from Condé Nast Traveler and recognition in the Michelin Guide American South.
“Chattanooga has already demonstrated its ability to deliver an exceptional Ironman 70.3 World Championship experience,” said Diana Bertsch, Managing Director, Ironman North America & World Championship Events. “From its stunningly scenic courses to the overwhelming community engagement, we are thrilled to return in 2027 and once again showcase this iconic destination to a global audience. This expanded partnership reflects our shared commitment to long-term success and continued growth, including the return of professional racing.”
Big Impact
In 2025, Ironman Chattanooga and Ironman 70.3 Chattanooga generated a combined $26.8 million in total economic impact to the region.
“The world’s best athletes deserve a world-class destination, and that’s exactly what Chattanooga delivers with endless outdoor adventure and the exceptional hospitality Tennessee is known for,” said Tennessee Department of Tourist Development Commissioner Mark Ezell. “Ironman will bring visitors – and the tax dollars they generate – from around the globe, generate millions in economic impact for local businesses and showcase the experiences that inspire travelers to return to Tennessee again and again.”
Race week in 2027 will include Ironman Village, athlete briefings, community activations and Ironkids races. The qualifying cycle begins July 5, 2026 with the Ironman 70.3 Jönköping European Championship, 70.3 Les Sables d’Olonne-Vendée and 70.3 Muskoka triathlons. Several athletes with the Team Rocket Tri Club of Huntsville will be competing in the Muncie 70.3 event in July.
The 2027 championship will be presented by Precision Fuel & Hydration.
