IRONMAN 70.3 Tours Metropole - Loire Valley

Arrive with a calm, repeatable routine: get a short warm-up in if the logistics allow, then spend a minute or two settling your breathing before you touch the start line. Seed yourself based on your swim pace to avoid early traffic—on a crowded swim, your first goal is positioning, not speed. In the first few minutes, run your stroke with a consistent cadence and sight only as needed so you don’t drift off-line while the pack is densest.

You’ll cover 1,909m in freshwater where temperatures can vary, so start slightly controlled and let your body temperature rise through the middle third. Expect the most common early challenge to be congestion—find clean water quickly, then settle into an efficient rhythm. Keep an eye on wind impact on surface conditions; when conditions are breezy, waves and chop can change how your body rotates and how easy it feels to stay on line. Fueling during the swim isn’t the focus—use the swim to arrive fueled for the first hour by taking in your planned pre-race nutrition and being ready to drink on the bike immediately after T1.

Your key T1 flow is speed with organization: get out of the swim, manage wet-foot transitions efficiently, and avoid lingering. As you mount, focus on smooth, stable power delivery for the first 10–15 minutes rather than chasing speed—flat/fast courses reward discipline. Have your first drink and first carbs ready so you begin fueling early, before thirst and fatigue force mistakes.

Ride 87.4km on a flat/fast profile with 178m of elevation gain, so the course invites steady output and consistent cadence. With wind reported at 5 m/s from the W, be ready for subtle speed changes and crosswind effects—especially on any exposed stretches—by holding your position, relaxing your grip, and letting power lead instead of speed. Because it’s moderately warm (13.1–22.2°C range), start fueling early and keep fluid intake regular rather than “catching up” later. Use the target fueling rate of 90g carbs per hour, 750mg sodium per hour, and about 650ml fluid per hour, adjusting slightly only if you’re clearly under- or over-hydrated. Aim for smooth feeding while maintaining aerodynamics; steady intake beats big swings in the final third.

In T2, keep your focus on legs-on first: transition with quick steps, then settle into a controlled first 1–2km so the bike doesn’t “steal” your run rhythm. Your early goal is to feel powerful without turning the first kilometers into an all-out effort—flat/fast with only 49m gain is where pacing must be intentional. Start drinking early the moment you’re running; heat is moderate, and steady fluids prevent late-race fade.

Run 21.1km on a flat/fast profile with 49m elevation gain, so the course rewards a consistent cadence and disciplined effort. With moderate heat and wind from the W still influencing how exposed sections feel, expect your perceived effort to climb even if your actual speed doesn’t—use breathing and pacing cues rather than adrenaline. Fueling on the run should match the hydration/energy plan you executed on the bike; continue your planned intake cadence so you don’t arrive at the later miles empty. If any sections feel harsher due to wind exposure, slightly shorten your stride and keep your form tall rather than forcing pace changes that cost recovery. Keep an eye on stomach tolerance—consistent small intakes beat occasional large boosts.
