IRONMAN 70.3 Chattanooga

The IRONMAN 70.3 Chattanooga is one of the most popular half-Ironman races in the country, and for good reason. The swim takes place in the Tennessee River with a downstream current, the bike course winds through the scenic valley, and the run finishes along the riverfront at Ross's Landing.

Even if you're not racing, it's a spectacle worth watching. The swim start at dawn is dramatic, and the finish line atmosphere at Ross's Landing is electric with crowds cheering athletes across. The downtown area gets buzzing with energy all weekend.

If you're a spectator, stake out a spot along the riverfront run course or at the finish line. Restaurants downtown will be packed, so make reservations in advance.
