What this race demands

IRONMAN Wales requires an athlete to sustain output across a continuous 226 km triathlon comprising a 3.8 km swim, 180 km bike, and 42.2 km run in Tenby.

Total Endurance Capacity

The full-distance 226 km format demands prolonged aerobic output and extensive cardiovascular stamina to complete all three consecutive disciplines.

Multidisciplinary Pacing

Transitioning from a 3.8 km swim to a 180 km bike and finishing with a 42.2 km marathon run requires strict discipline management to avoid early fatigue.

Aim for 60 to 90 grams of carbohydrates per hour throughout the bike and run segments to match the demands of a continuous multi-hour effort.
