IRONMAN 70.3 Punta del Este

Plan a controlled start for the full 2,009m: get calm in your first strokes, settle your breathing, and avoid sprinting the first 100–200m. If you have any choice at the start, seed based on your ability to hold your target pace without getting repeatedly stalled. From the first buoy to the first real sighting, run a simple rhythm (consistent arms, steady kick, brief head-down/quick sight). In the final minutes, start thinking transition-to-bike: decide where you’ll grab cap/goggles if required, and aim to exit without a big “stand-up and panic” surge so your legs feel ready for the first pedal strokes.

You’re swimming 2,009m in water that’s typically around 23.7°C—comfortable but still something to respect with a smooth warm tempo rather than a hard opener. With typical sea-breeze conditions at the venue, sighting matters: use short, frequent checks so you don’t drift with wind and current influence. The goal is to stay organized—if you get boxed in early, breathe a touch lower and get your tempo back as soon as you find clear water. Fueling during the swim is usually minimal; focus on taking fluids/carbs after you’re on the bike so you hit the bike/run targets steadily rather than trying to eat in the water.

Your T1 flow should be simple and repeatable: exit, get stable, secure gear, then move into the bike feeling smooth—not frantic. Before you actually load power, spin the first minute to re-establish rhythm and get your breathing down after the swim. Focus on hydration and getting positioned correctly before intensity: settle into your cadence and don’t chase speed right away, especially with a 6.6 m/s wind pushing from the E. In the transition itself, keep your eyes up while grabbing shoes/helmet so you don’t lose time with fumbling.

Ride the 90km bike as a steady effort with weather awareness: the wind is typically from the E at about 6.6 m/s, so expect at least some crosswind and headwind/exposed sections where speed can drop even if your power stays steady. Aim to prevent the “brake pedal” problem—when it’s windy and bumpy-feeling, keep your upper body relaxed and let your legs do the work while you maintain consistent effort. Fueling should match the race targets: take in about 90g carbs per hour with ~1,000mg sodium per hour and roughly 800ml fluid per hour, starting early and staying consistent (don’t front-load everything in the first third). If conditions feel hotter in sheltered versus exposed areas, adjust how much fluid you’re taking in while keeping carbs/sodium aligned with your plan.

In T2, expect your legs to feel “recruited” rather than naturally ready—shake out your arms, take a few quick, controlled steps, and find an easy first-kilometer rhythm before settling into pace. Don’t sprint the first stretch; with moderate heat and wind lingering from the bike, the early surge is the fastest way to overheat and fade. Get your first drink on board early in the run so your hydration stays on schedule rather than catching up later.

Run 21.1km with a pacing mindset that respects moderate heat (air temperatures typically range 18.8–25.4°C). The east wind and any lingering effects from the bike can create uneven conditions—plan to keep your effort steadier than your speed, especially in more exposed segments. Fuel to your targets during the run as well: aim for about 90g carbs per hour with ~1,000mg sodium per hour and roughly 800ml fluid per hour, using aid stations proactively instead of waiting until you’re thirsty. If you feel yourself cooling in windy patches, that’s not a license to speed up—just keep cadence and hydration steady; if you feel overheated, prioritize fluid first while maintaining carbs/sodium so you don’t stall your energy availability.
