IRONMAN 70.3 Chattanooga
A fast Tennessee River swim, rolling Georgia hills, and a riverfront finish line — your first big half-distance adventure in one of the South's most welcoming race cities.
Where it is
CHATTANOOGA, TENNESSEE
Is this your race?
Chattanooga is a genuinely beautiful first half-Ironman — but the summer heat and hilly bike course mean you'll want a solid base before you show up.
✅ You’ll love it if…
- You've been swimming consistently and feel comfortable in open water (rivers move — that's part of the fun!)
- You've done some hilly rides and know how to pace yourself on climbs
- You thrive in warm weather and have practiced training in the heat
- You love a city-center race atmosphere with crowds cheering on the riverfront
⏳ Build up first if…
- You're brand new to open-water swimming — get some river or lake practice in before race day
- Your longest bike ride is still mostly flat — add some hill sessions over the next several months
- Heat is a concern for you — build in heat-acclimation training as summer approaches

The course, demystified
Three legs, one unforgettable day: float downstream on the Tennessee River, roll through the Georgia countryside, then run two loops along the riverfront as the crowd pulls you home.
El nado empieza río arriba en el Tennessee River y termina en Ross's Landing — el río te lleva, lo que hace que muchos nadadores principiantes completen esta etapa más rápido de lo esperado. The swim is point-to-point, meaning you start at one spot and the current gently carries you downstream to the finish. You'll swim a short section upriver first before turning and riding the current all the way to Ross's Landing. Sighting (lifting your head to check where you're going) is still important even with a current helping you.
The bike course leaves downtown Chattanooga, heads into northern Georgia, and takes you through rolling countryside with long climbs and rewarding descents. Total elevation gain is 2,218 feet — think of it as several long hills rather than one giant mountain. The scenery is genuinely stunning, which helps when your legs are working hard.
The run is two loops along the Riverwalk and Riverfront Parkway — mostly flat to gently rolling, right in the heart of downtown. Two loops means you'll pass the finish area and the loudest crowds twice, which is a huge mental boost. Spectators are concentrated here, so expect noise, cowbells, and people cheering your name.

🏨 See stays · affiliateLookout Mountain / St. Elmo
Popular with athletes who want a head start toward the bike course and a slightly quieter base. A bit further from the swim start, so factor in race-morning travel time.

Bringing a support crew?
Chattanooga is one of the best spectator races out there — the compact downtown layout means your crew can see you multiple times without a car.
- Ross's Landing: watch the swim finish and both transitions — this is the heart of the race.
- Riverfront Parkway / Riverwalk: the run course passes here twice, so plant yourself here and cheer athletes on both loops.
- Downtown Chattanooga streets near the bike exit: catch athletes heading out on the bike and returning — two sightings for the price of one corner.
- The finish line at Ross's Landing: the most emotional spot of the day. Be here for the final miles of the run.
