Chattahoochee Challenge Sprint Triathlon and Duathlon

The Chattahoochee Challenge Sprint Triathlon and Duathlon is held in Columbus, GA, with event activities staged near 801 Front Ave. The event is organized by TriColumbusGa and includes multiple race formats and relay options.

Race formats include:

  • Sprint triathlon: 500m swim, 12 mile bike, 5k run
  • Duathlon: 1 mile run, 12 mile bike, 3.2 mile run
  • Floatie division: 500m float, 12 mile bike, 5k run

The swim is a 500m downstream section of the river. Athletes may start via a water slide; all slide entries must be feet first. Use of steps to the water is permitted as an alternative. River depth is approximately 4 to 6 feet and starts are conducted in a time-trial format, with athletes entering individually.

The 12 mile bike course begins and ends on the Columbus Riverwalk. The run is a very flat one-loop course of about 3.1 miles. An aid station is located roughly 200 yards out of transition and will be passed twice.

Awards are given by male and female categories in age groups from under 14, then five-year increments up to 70 plus, plus top overall and relay awards. The floatie division has awards for the top three floaties. Each participant receives a medal and a t-shirt, and triathletes are provided a swim cap.

Race management may modify or cancel elements of the event for hazardous weather. No refunds are offered; deferrals may be considered with supporting documentation. Visit the organization's website for the most recent information.
