The race
The course
No course maps for this race. IRONMAN publishes no downloadable route for any leg of this race, 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.
One clockwise loop of Lake Monona from Law Park Beach to the concrete boat ramp, with buoys every 100 yards so sighting is straightforward. Rolling start, self-seeded by your estimated swim time. Then you run up the Helix into T1.
A 56-mile tour of Madison and the country around it. The official page describes it in one sentence and states neither a lap count nor an elevation figure, so neither appears here.
An out and back through downtown Madison finishing in front of the Capitol building. The official page does not state a lap count.
Not yet confirmed for this edition: bike lap count, run lap count, 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.
Course details verified against the official IRONMAN 70.3 Wisconsin course page on 14 August 2026. Courses change; the official page is always the last word.
