What this race demands
IRONMAN Wisconsin demands sustained pacing across a 226 km triathlon covering a 3.8 km swim, 180 km bike with 1672 m of elevation gain, and a 42.2 km run.
Aerobic endurance
The full-distance format requires efficient pacing over many hours to sustain output from the swim through the final miles of the marathon.
Bike climbing strength
The 180 km bike leg includes 1672 meters of elevation gain, requiring consistent power output on rolling terrain without overly spiking metabolic cost.
Run durability
The 42.2 km run demands late-race muscular endurance and stability after a demanding swim and bike profile.
A sustained intake of 60 to 90 grams of carbohydrates per hour is required across the duration of the event to maintain energy availability and prevent late-race depletion.
