Event Overview
IRONMAN 70.3 Chattanooga, affectionately known as 'Chappy' by the triathlon community, is one of the most popular half-distance races in the United States. Taking place on May 17, 2026, in the 'Scenic City' of Chattanooga, Tennessee, this race is famous for its unique point-to-point downstream swim and its stunning bike course that crosses into Georgia. The atmosphere in downtown Chattanooga is vibrant, with a finish line at Ross’s Landing that feels like a professional stadium environment.
Course Details & Terrain
The Swim: Tennessee River
The 1.2-mile swim is a major draw for this race. It is a point-to-point, downstream swim in the Tennessee River. Because you are swimming with the current, times are significantly faster than in still-water lakes. It’s an ideal setting for those who find the swim to be their weakest discipline.
The Bike: Rolling Hills and High Speed
The 56-mile bike course is a single loop that takes athletes south out of Tennessee and into the rolling hills of Chickamauga, Georgia. Expect about 2,500 feet of elevation gain. The roads are generally smooth, but the 'rollers' can be deceptive. Constant gear shifting is required to maintain a steady cadence and power output.
The Run: The Bridges and Hills
The 13.1-mile run is where the race is often won or lost. It is a two-loop course that includes crossing the Tennessee River via the Walnut Street Bridge—one of the longest pedestrian bridges in the world. The run is not flat; it features several punchy climbs that will test your tired legs after the bike.
Who Should Enter? (Beginners vs. Experienced)
For Beginners
Chattanooga is the perfect 'first-timer' IRONMAN 70.3. The downstream swim removes much of the anxiety associated with the start of a triathlon, and the bike course is manageable for those who have trained on moderate hills. The massive crowd support throughout the city ensures you’re never alone in the 'dark moments.'
For Experienced Athletes
For the podium hunters, Chattanooga is a tactical race. The fast swim means the field stays relatively compressed, making the bike leg highly competitive. Athletes must be proficient at climbing and descending while staying in the aero position to maximize speed on the Georgian roads.
Coach Raye's Race-Day Pro Tips
- Swim the Middle: In the Tennessee River, the current is typically strongest in the center of the channel. While it adds a bit of distance to stay away from the banks, the speed boost from the faster water usually results in a better overall time.
- Don't Hammer the Chickamauga Rollers: It’s easy to push too many watts on the short climbs in Georgia. Instead, focus on a high cadence and 'cresting' the hills before getting back into your big gear. Over-riding the bike here will destroy your legs for the hilly run.
- Cooling on the Run: Chattanooga can be very humid in May. Use every aid station for cooling—ice down the trisuit and water on the head—even if you don't feel 'overheated' yet. Managing core temperature early on the run is the key to avoiding a late-race fade.
