Where to watch

Folks can cheer on the athletes at several designated spectator zones along the courses. You can also support the participants by watching the live broadcast and more.

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

Traffic + closures

These roads will be closed on Wednesday, May 15 at 9 a.m. through Monday, May 20 at 5 a.m.:

  • Riverfront Parkway (between Aquarium Way + Molly Lane)
  • Chestnut Street (between Aquarium Way + Riverfront Parkway)
  • Power Alley (from the parking lot to Riverfront Parkway)
  • Southbound Veterans Bridge ramp to Riverside Drive

Expect several other closures and detours during the race times on Sunday. Police will be on-site directing traffic.

Note: Watch for parking restrictions around these areas that will be in effect from Saturday, May 18 at 6 p.m. to Sunday, May 19 at 8 p.m.

Avoid the crowds

On Sunday, you’ll want to avoid the areas along the Tennessee River (think: Riverside Drive, the 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.
