Event Overview
Taking place on September 27, 2026, IRONMAN Chattanooga has earned its reputation as one of the most beloved stops on the North American circuit. Known as the 'Scenic City,' Chattanooga provides a breathtaking backdrop of the Tennessee River and the Lookout Mountain foothills. What makes this race unique—and a bit of a cult classic—is the distance. Unlike the standard 140.6 miles, Chattanooga features a 116-mile bike leg, bringing the total to 144.6 miles. The local community support is unrivaled, with a finish line atmosphere at Ross’s Landing that rivals the World Championships.
Course Details & Terrain
The Swim: This is a point-to-point, 2.4-mile swim in the Tennessee River. It is famous for being a 'down-current' swim, making it one of the fastest IRONMAN swims in the world. Even novice swimmers can see significantly faster times here than in a lake or ocean.
The Bike: The 116-mile bike course takes athletes out of Tennessee and into North Georgia. It consists of two loops of 40+ miles after an initial stick. The terrain is 'rolling,' meaning there are very few flat sections, but no massive mountains. The cumulative elevation gain is significant, and the extra 4 miles over the standard distance require a disciplined fueling strategy.
The Run: The 26.2-mile run is a two-loop affair that is notoriously difficult. It crosses the Veterans Bridge and the Walnut Street Pedestrian Bridge, offering great views but plenty of elevation change. The 'Barton Avenue' climb is the signature challenge of the run—a steep hill that athletes must tackle twice.
Who Should Enter? (Beginners vs. Experienced)
Beginners: If you are worried about the swim cutoff, Chattanooga is your race. The current provides a massive safety net. However, you must be prepared for a longer day in the saddle. It’s a great first-time full-distance race for those who enjoy hilly training.
Experienced: For those chasing a PR, the fast swim sets you up well, but the 116-mile bike means your 'standard' IRONMAN time goals need to be adjusted. It is a 'strength' course rather than a 'pure speed' course. If you excel at high-cadence climbing and heat management, you will thrive here.
Coach Raye's Race-Day Pro Tips
- Master the 'Fast' Swim Sighting: Because you are moving with the current, you will approach bridge pilings and buoy turns faster than usual. Sight frequently to ensure you stay in the swiftest part of the channel (usually the middle) until you need to exit at Ross's Landing.
- The 116-Mile Fueling Plan: Most athletes plan nutrition for 112 miles. That extra 4 miles can take 12-20 minutes depending on your pace. You must carry an extra 200-400 calories and additional electrolytes specifically for that final stretch of the bike to avoid starting the run in a deficit.
- Walk the Barton Avenue Aid Station: The Barton Avenue hill on the run is steep. Unless you are an elite runner, use the aid station at the hill to power-walk, hydrate, and lower your heart rate. You will often make up more time by running strongly on the subsequent descent than by grinding up the hill at a high heart rate.
