IRONMAN 70.3 Eagleman

Arrive ready to move immediately in the water: do a short, progressive warm-up (easy swim to a few steady pick-ups) so your arms feel “on” when you enter. Get into your seed as cleanly and calmly as possible—don’t fight for position in the first minutes if you’re not at your target pace. For the first 3–5 minutes, settle into an even stroke rate, aim for controlled breathing, and keep your focus on smooth, repeatable form rather than early speed. As you approach the exit, sight frequently, stand up gradually, and prepare to move efficiently into your T1 flow.

You’re swimming 1917 m in water that’s around 24.9°C and possibly non-wetsuit—so prioritize comfort and stability in your stroke. With typical conditions, the main challenge is staying relaxed enough to save energy for the 90.6 km bike; avoid sprinting to “win” space early. The safest approach is to swim slightly under control, then gradually build into your effort as you find rhythm. Fueling during the swim isn’t the focus; plan to be ready to drink/eat immediately after you hit the bike, and ensure you exit the water composed and hydrated.

Use T1 to make your transition quick and functional: get your gear set so you can mount without hunting, and keep your first 1–2 minutes gentle while you find cadence. As you mount, gradually increase power/effort—don’t jump into full speed immediately. Your goal is to feel “connected” to the bike quickly on this flat/fast 90.6 km course while respecting the SW wind. If you’re targeting a steady ride, start organizing your fueling and hydration timing immediately after you’re comfortable in your position.

This is a 90.6 km flat/fast bike with only 35 m of elevation gain, so aerodynamic efficiency and steady power pacing matter more than climbing skills. Expect hot air temperatures (19.3–27.3°C) and a SW wind around 4.9 m/s, which can affect control and comfort: into the wind, stay disciplined with power so you don’t spike; with any crosswind components, keep your steering smooth and avoid sudden inputs. Fueling target is aggressive consistency: take in 90 g carbs per hour, 1000 mg sodium per hour, and about 800 ml fluid per hour—aim to start early and maintain that rhythm rather than “catching up” late. Because the course is fast, it’s easy to overcook the first half; commit to even effort and use drink/gel timing to stay ahead of thirst and heat stress.

Plan your T2 so your legs feel transition-ready: after dismount, be smooth and take 20–30 seconds to re-center your breathing before you accelerate. The first 1–2 minutes of the run should feel controlled—your job is to find a sustainable stride on fatigued legs, not to chase early pace. With the run being flat/fast (21.6 km, 27 m elevation gain), you’ll likely feel “good” early; resist going too hard if the heat is already climbing. When you settle in, lock onto a rhythm you can hold through the steady middle miles.

You’ll run 21.6 km on a flat/fast course (27 m elevation gain), but hot conditions can turn it into a physiological grind. The SW wind (~4.9 m/s) can help at times, yet heat stress is still the dominant limiter—so pace conservatively early and build only if you feel stable. Hydration and sodium matter: follow your fueling targets (90 g carbs and 1000 mg sodium per hour, plus ~800 ml fluid per hour) so your body doesn’t fall behind during the hottest periods. Take in fluids regularly, especially on exposed stretches; if you feel yourself getting “dry” (thicker throat, reduced comfort), increase sips rather than waiting for a full thirst hit. Focus on controlled form: quick feet, tall posture, and steady breathing—this course rewards rhythm.
