Ironman Wisconsin is a full-distance Ironman triathlon in United States, part of the Ironman calendar. The next edition is on 13 September 2026. The course is 3.8 km of swimming, 180 km on the bike and 42.195 km of running.
Climbing adds up to 2171 m, 1965 m on the bike and 206 m on the run, a demanding profile for the distance. The course is described as hilly.
Water temperature is typically around 24 °C, inside the wetsuit-optional range for age-group athletes, who may wear one up to 24.5 °C.
Pacer Quest rates Ironman Wisconsin as Hard: 2171 m of climbing (high); finishers +5% slower than the average Ironman. The rating is automatic and compares total climbing for the distance, water temperature and, where results exist, how finishers compare with the average for that distance.
At the 2025 edition, 40 qualifying slots were shared among 1313 ranked finishers, with slots allocated by age-graded rank under IRONMAN's performance-based system. For example, a M40-44 athlete needed roughly 9:46:11 and a F40-44 athlete needed roughly 9:45:13 to be inside the line.
