IRONMAN Wisconsin 2026
Two laps of Lake Monona, a hilly two-lap ride through Wisconsin farmland, and a two-lap run around the State Capitol. Famous for the Helix.
4 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 Wisconsin.
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 Helix is a small thing that people obsess over and the farmland loops are the big thing that decides the day. Train rolling hills on tired legs, not spiral ramps.”
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.
Two clockwise laps of Lake Monona from a self-seeded rolling start. You stay in the water between laps rather than running the beach, then climb the Helix, the spiral car ramp at Monona Terrace, on your way into T1.
Down the Helix, out south and west, then two hilly laps through the farmland. The climbs are where the spectators stand, particularly in Verona, and then it is one last push back up the Helix to the dismount line at the top.
Two laps through downtown Madison, out through Camp Randall Stadium and past the UW Lakeshore Nature Reserve by University Bay, then back around the Capitol building.
Not yet confirmed for this edition: bike 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.
