IRONMAN 70.3 Sunshine Coast

Get settled early and aim to be calm in the first minutes—start with easy rhythm strokes, keep your breathing steady, and let your eyes lock onto clear sight lines. If you’re seeded with mixed abilities, expect slower swimmers briefly; draft behind moving feet or keep a controlled gap so you’re not burning matches in the first stretch. Focus on smooth technique right away: quiet head, consistent catch, and a pressure-free tempo until you feel the pace settle.

You’ll swim 1,913 m in freshwater where temperature varies—treat the first part as a warm-up set, because cold-to-moderate starts can spike heart rate fast. The main goal is to swim straight, avoid unnecessary detours, and ride the pack intelligently without constantly changing lanes. Fueling isn’t the priority during the swim; just set up your transition by staying efficient and controlled. If conditions feel choppy or crowding increases, shorten your stroke slightly and emphasize balance so you don’t drift off line.

Plan your T1 flow: make sure your bike is set up for fast mounting (clothes, helmet, shoes), then keep your transition calm—no wrestling, no overthinking. As you mount, accelerate gently for the first minutes while you find your target cadence and wind-handling position. Once stable, start building to race effort gradually so you’re not spiking power right as the bike phase begins.

The bike is 91.3 km with 338 m of elevation gain on a flat/fast profile, so you can keep things consistent—think steady power and minimal “thrash.” With wind at 4.6 m/s from the S, expect the pacing and comfort to change subtly across different sections; stay aerodynamic into the wind where it matters, then relax your grip and posture slightly when the ride turns easier. Your fueling target is 90 g carbs per hour, 750 mg sodium per hour, and about 650 ml fluid per hour—start early and keep taking in a smooth cadence rather than waiting for thirst. Aim to match your drinking to how the wind and effort affect your sweat rate, using frequent small intakes to stay on schedule.

For T2, be ready for “heavy legs” right away—your first goal is technique and tempo, not speed. When you rack and approach the run start, start with 10–15 seconds of quick posture resets: tall hips, relaxed shoulders, and short, controlled steps to get your stride underneath you. Mentally commit to a steady build for the first few kilometers so you don’t go out too hard off the bike.

You’ll run 21.7 km with 63 m of elevation gain on a flat/fast profile, which makes it a pacing execution race. With moderate heat (air temp range 13.7–23.2 C), manage intensity early: if you feel great in the first third, resist the urge to surge—save the effort for maintaining form as fatigue climbs. Drink and eat to support your pacing—keep your intake consistent rather than reacting to gut feelings mid-run. The course stays fast, so the challenge is holding mechanics (upright posture, efficient stride, steady breathing) while the steady wind and heat start to add up.
