IRONMAN 70.3 Versailles

Get in warm if the morning is cool (14.8°C); do a gradual build-up so your first 5–10 minutes feel smooth, not rushed. Line up based on your swim goal/pace—if you’re unsure, seed to avoid getting kicked up and wasting effort. Use the first few minutes to settle your stroke rhythm, sight a couple times early, and relax your grip so you don’t gas in the opening meters.

Swim 1903 m in freshwater where temperature varies, so assume it could feel colder at the start and warm later. Breathe rhythmically and keep your effort controlled through any congestion; the fastest swimmers will move through without you needing to chase every body. Because there’s no wind-driven wave guidance for the swim, your biggest variable is how your arms feel once the water temperature settles in—start a touch easier than you think for the first chunk. Fueling happens off the swim, so focus on hydration timing for the transition: be ready to move into the bike calmly and don’t over-sip in the water if there are any delays at the start.

Plan for a quick, repeatable transition: exit the swim, run to your bike with steady cadence, mount smoothly, and get moving without standing up too long. In T1, have your setup dialed—shoes and helmet secure before you commit to speed. Off the mount, keep power controlled for the first segment so your legs transition from swim to bike; take 3–5 minutes to get rhythm, then start pressing into your target effort.

Ride 90 km on a rolling course with 620 m of elevation—expect repeated changes in effort, not one long climb. With NW wind at 4.6 m/s, crosswinds and small gusts can nudge you; stay relaxed in your upper body and make your steering smooth rather than reactive. Aim for steady power through the rolling terrain: downhills are for maintaining form and controlling speed, not for coasting long or standing to chase gains. Fuel and hydration target throughout the bike is carbs 90 g/hour, sodium 750 mg/hour, and fluid 650 ml/hour—take it consistently (not in one or two big grabs), and match your drink intake to wind/effort so you don’t under-sip during the “easy” sections.

In T2, expect your quads and calves to feel a bit unfamiliar after 90 km—your job is to find smooth turnover before you chase pace. Do a controlled jog for the first few minutes, focus on relaxed shoulders and quick feet, and let breathing settle. If you feel heavy, shorten stride slightly and keep the effort steady until the rolling terrain starts to feel natural.

Run 21.2 km with 82 m of rolling gain—this is about pacing discipline more than flat-out speed. With air temperatures ranging up to 24.3°C and moderate heat, start cooler than you think and avoid letting early adrenaline turn into a late fade. The NW wind can affect you on exposed sections—when it’s in your face, keep effort controlled and let pace drop rather than forcing it; when it’s with you, don’t sprint the tailwind, just hold form. Continue your fueling strategy during the run to match your plan; the most common failure is arriving under-fueled and trying to “fix it” late. Use the rolling profile to your advantage by keeping effort even on uphills and using controlled speed on downhills—no braking that turns into heavy legs.
