IRONMAN Chattanooga
IRONMAN Chattanooga on 27 September 2026 is a full-distance race with a downstream swim: 3.8 km with the current in the Tennessee River, then 180 km in the countryside north of the city and 42.2 km through downtown.
The swim is assisted enough to distort comparisons. If you are weighing finish times from here against other full-distance races, the difference sits in the river rather than in the field.
The bike does not return the favour. The roads through the Tennessee and Georgia ridges roll constantly, with enough short climbs to make a steady power plan hard to hold, and the run then crosses the river twice a lap with a climb up into the north-shore neighbourhood each time.
Late September in Tennessee is still warm and humid. The heat here has ended more races than the elevation has, and the run is the part of the day where it arrives.
