IRONMAN Jacksonville brings a bold new challenge to Florida’s Atlantic coast — in a city known for its athletic spirit, vibrant culture, and deep community pride. This scenic course blends fast-paced urban roads with the breezy rhythm of the St. Johns River, offering a race experience that’s as dynamic as it is rewarding.
IRONMAN Jacksonville blends the charm of the South with the thrill of city racing, offering athletes a fresh and fast full-distance experience in the heart of Northeast Florida.
Your day begins with a downriver swim in the St. Johns River—smooth, scenic, and built for speed. Then, you’ll power through a flat, fast bike course that cruises past urban landmarks and into the vibrant core of the city. The run is where it all comes alive: cross the bridge, take on a few rolling hills, and push through five unique boroughs, each bringing its own rhythm, personality, and cheering crowds.
Whether you’re chasing your next PR or stepping up to your first IRONMAN, Jacksonville delivers the perfect balance of energy, city life and coastal beauty to keep you moving forward.

The race did great with the unplanned heat. Super volunteers and aid stations. No long stretches on the bike without aid. Great run thru town on a flat three lap course. Awesome event and it was just the first year!
