IRONMAN Chattanooga 2026
A downstream Tennessee River swim, three loops on US-27 with a dedicated lane and 4,300ft of climbing, and a two-lap run finishing at Ross's Landing.
6 weeks to race day: the sharpening window
A full build no longer fits, but a sharp one does. This close in, the job is specificity and freshness: race-pace touches, open-water or brick rehearsal, and a taper your nervous system actually absorbs. No heroics; arrive fresh.
Building for this one? Ironman training plan covers the sessions, the weekly shape and how the block is paced. The R.A.C.E. Framework explains why it is built that way.
Start my Road to IRONMAN Chattanooga.
Commit to the date and the work gets a shape: your countdown starts, the emails arrive in step with your build, and the app anchors a recovery-led block so the final week lands exactly on race day.
One confirmation email, then the road begins. Registering for the race itself stays with the organiser.
“The swim flatters everybody and the bike tells the truth: 4,300 feet across three loops, and the third one is where the day is decided. Ride the first two loops like you have another one to do, because you do.”
The race
The course
No course maps for this race. IRONMAN publishes no downloadable route for any leg of this race, only a live tracker that runs on race day, so there is nothing to draw a course map from. Everything below comes from the official course page, checked on the date at the foot of this section.
A rolling start off a dock 2.4 miles upstream of transition, then downstream almost the whole way to Ross's Landing, with only the final stretch after the red turn buoy against the flow. Expect a fast split for reasons that have nothing to do with your swimming. Spectators walk alongside on the Riverwalk. Mid-70s water makes the wetsuit a race-morning call.
South to Martin Luther King Boulevard, onto US-27, then north through Red Bank to Soddy Daisy for three loops. 4,300 feet of climbing across the leg, on fresh tarmac with a dedicated lane the whole way and the Cumberland Plateau alongside.
Two loops through downtown, the Tennessee Riverwalk, over Veterans Bridge to the North Shore and back down Riverfront Parkway to finish at Ross's Landing.
Not yet confirmed for this edition: transition locations, run elevation gain, cut-off times, water temperature history. We publish these only once they are on the official course page, so check there before you pace off anything here.
