IRONMAN Vitoria-Gasteiz

Sunday, 12 July 2026

IRONMAN Vitoria-Gasteiz is a 3.8 km freshwater swim followed by a flat/fast 180 km bike (832 m gain) and then a 42.2 km run—your race will be won by steady pacing and disciplined fueling in moderate heat with a light-to-moderate N wind.

T1 — swim to bike

For a clean swim→bike flow, keep your routine simple: shoes and nutrition in place, mount efficiently, and take the first minute to settle into cadence and aero position. As you roll out, avoid the temptation to hard-accelerate off the mount—get your heart rate down to race target and establish your fueling early. If you’re navigating a windy start section, stay relaxed and keep steering inputs smooth so the bike feels stable under the N wind.

During the bike

The bike is 180 km with 832 m of total elevation and a flat/fast profile, so the course tends to reward consistent power and steady aero efficiency rather than repeated surges. With N wind at about 5.1 m/s, expect that some sections will feel like head/crosswind gusts depending on your road orientation—stay within your power/effort and don’t chase speed when the wind changes. Fueling is built for endurance: target 90 g carbs per hour, 1000 mg sodium per hour, and about 800 ml fluid per hour, using regular, small intakes rather than waiting until you feel thirsty. Use the flatter stretches to lock into your breathing and cadence, and if you hit slightly tougher wind moments, shift effort to torque/cadence consistency instead of pushing watts higher.

Closing notes

As you near T2, keep your effort controlled—smooth watts beat a last-minute push when the run is next. Start thinking about hydration going into the run: if you’re behind on fluid or sodium, make the last appropriate intake count without forcing large quantities at once. When you get off the bike, step into T2 ready to “spin the first minute” rather than stomp—your legs should feel heavy, and that’s normal.
