IRONMAN Chattanooga

IRONMAN Chattanooga takes place in Chattanooga, Tennessee, and is known as the "Engine of Endurance." The event features a course designed through scenic landscapes, incorporating a river swim, a rolling bike segment, and a run through the downtown area.

The competition consists of three primary disciplines:

  • Swim: A downriver course in the Tennessee River.
  • Bike: A rolling course through the scenic Tennessee landscape.
  • Run: A rolling course that leads through the vibrant downtown and across local bridges.

The Tennessee River swim is noted for its fast-flowing current, which often assists athletes in achieving personal best times. The bike and run segments utilize the rolling terrain characteristic of the region. The race is a qualifier for the 2027 IRONMAN World Championship.

Average environmental conditions for this location in late September typically include air temperatures ranging from 18 °C (44 °F) to 28 °C (54 °F). The average water temperature in the river is approximately 24 °C (76 °F).

The event is supported by a significant community presence and offers various experiences for participants and spectators, including an IRONKIDS race and several local TriClub activities. Accommodations and local outdoor trails are located near the host city hub. Visit the organization's website for the most recent information.
