Where to watch

Folks can cheer on the athletes at several designated spectator zones along the courses. A complimentary shuttle service will also be provided to take supporters to the bike course in Chickamauga, GA.

Pro tip: Download the interactive Ironman Athlete Tracker App so you can follow the athletes in real time.

Traffic + closures

Riverfront Parkway (between Molly Lane + Aquarium Way) will be closed now until 9 a.m. on Monday, Sept. 26.

Expect several closures and detours during the race times on Sunday + police will be on-site directing traffic. See the full list of closures.

Avoid the crowds

On Sunday, you’ll want to avoid the areas along the Tennessee River (think Riverside Drive, the Tennessee Riverwalk, Ross’s Landing, and Barton Avenue). The bike race travels through NorthShore to northern Georgia, so expect crowds in the St. Elmo area as well.

We recommend spending the day in Hixson, East Ridge, or Brainerd. Looking for dinner plans? Side Track Restaurant is one of our favorite hidden gems tucked away on Hixson Pike.
