IRONMAN Vichy

Get to the start with time to settle your breathing and calm your nerves. Do a short warm-up that gradually increases intensity (a few faster strokes) so your first 10–15 minutes feel smooth rather than rushed. Seed yourself based on your swim pace, aim to avoid being trapped in the slowest packs, and when the start goes, find clean water quickly so you can lock into rhythm.

The swim is 3,787 m in freshwater with temperature that varies, so treat it like a controlled effort: start slightly conservative, then build to a sustainable stroke cadence. With wind conditions that matter more later, your main variable in the swim is how the water feels—stay smooth through the first portion, and avoid repeated surges that will cost you on the bike. Prioritize consistent breathing and efficient turns/lines to reduce extra distance. Fueling during the swim is minimal for most athletes—use this leg to execute pacing, then be ready to transition into drinking and carbs immediately on the bike.

Your T1 goal is to go from swimming mechanics to cycling control fast: rack-clean, transition quickly, and get your first bike strokes feeling stable. As you remount, focus on smooth cadence and a relaxed upper body—don’t sprint out of the chute. For the first minutes, settle into your fueling rhythm and check you’re actually drinking/eating as planned before the climbs stack up. If it feels hotter than expected, lower effort slightly early so you can hold power (or speed) when the course demands it.

The bike is 180.4 km with 1,702 m of elevation gain and a hilly/climbing profile, so the course will reward a steady approach on the grinders and a composed effort on the descents. With wind reported as 3.6 m/s from the NW, expect it to influence stability and comfort—stay slightly more conservative with steering and body position, especially when you’re exposed. Heat is a key factor here (air temp roughly 14.9–27°C), so start drinking early and keep your core cool even when you feel you’re “fine.” Stick to the provided fueling target: 90 g carbs, 1,000 mg sodium, and 800 ml fluid per hour—split it into frequent intakes rather than one big hit. Use the climbs to eat and drink consistently; use descents to quickly reset and keep cadence smooth, then resume effort without panic-riding when the grade changes.

T2 is where you set the tone. Your first priority is to get the transition done cleanly and start the run with legs that feel “connected,” not explosive. Expect the first few hundred meters to feel heavy—keep your stride short, posture tall, and focus on even breathing. Use this early stretch to lock into your run pacing so you don’t overrun the effort in the heat-building conditions.

The run is 42.2 km with an unknown elevation profile, so plan to treat it like a long effort: settle early and keep your pace controlled. Heat is likely to be significant (air up to ~27°C), so manage it by staying on top of hydration and taking in carbs regularly—don’t wait until you feel thirsty. Because the bike has 1,702 m of climbing, anticipate fatigue patterns: watch your form as the calves/hips get tired, and avoid letting your stride shorten too abruptly. If you feel a surge of energy, resist using it—save the “gear change” for late-run execution rather than early damage. Aim for steady intake and even pacing throughout the full 42.2 km.
