IRONMAN 70.3 New Zealand

Arrive early and get 5–10 minutes of easy warm-up in the water if it’s available, focusing on smooth strokes rather than speed. When you line up, seed honestly: you want clean feet for the first half of the race rather than repeatedly escaping contact. For the first few minutes, start controlled—your goal is to settle your breathing rhythm and find space, because the distance (1899 m) adds up quickly if you go out too hot.

You’ll swim 1899 m in freshwater, with temperature varying day to day. Expect that early pacing matters: get into a steady cadence and use sighting to stay efficient, especially if conditions create chop or visibility shifts. If the water feels rougher than expected, prioritize a consistent stroke rate and longer, calmer body position rather than trying to power through every bump. Fueling starts after the swim—during the swim itself you won’t realistically take in the full targets, so plan to begin fueling/fluids immediately on the bike to hit 90 g carbs, 600 mg sodium, and about 500 ml fluid per hour from your bike start.

In T1, go for functional speed: exit the water cleanly, move quickly through the first steps, and get your bike shoes on without fighting your kit. Assume the transition may feel a little chaotic—your job is to stay methodical: glasses/helmet on correctly, shoes secured, and bottle(s) where you can grab them without searching. As you mount, spin easy for the first minutes and let your legs “wake up” before you settle into power/effort. The 89.2 km rolling profile rewards controlled early pacing so you’re not building debt on the first climbs.

Bike 89.2 km with 584 m of elevation gain on a rolling course, so you’ll be repeatedly turning big efforts into short recoveries. Use the terrain: keep effort smooth over the first rollers, then work a steady tempo on climbs rather than spiking power; on descents and faster sections, stabilize and breathe before you push again. Wind from the SW at 5.6 m/s can affect stability and headwind effort on exposed portions—stay relaxed in your upper body, keep a steady line, and avoid overcorrecting when crosswind hits. Fueling plan is straightforward and consistent: target 90 g carbs, 600 mg sodium, and about 500 ml fluid per hour—take it before you feel behind, and keep drinking even if you don’t feel very thirsty (moderate heat can still dehydrate you).

In T2, prioritize a quick bike-to-run changeover: rack down smoothly, dismount efficiently, and focus on getting your footing under you immediately. Off the bike, expect your legs to feel heavy for the first few minutes on a flat/fast course—let that happen and resist the urge to sprint the opening kilometer. Your strategy is to gradually build from controlled to strong as your rhythm locks in.

The run is 20.7 km with 48 m of elevation gain and a flat/fast profile, which means your speed will come more from pacing discipline than from route difficulty. Use the first portion to settle your cadence—aim for steady breathing and smooth strides, then build gradually as the course flattens out and your legs loosen. With moderate heat and SW wind, you’ll often feel “fine” while still losing fluid—so keep your hydration and sodium consistent through the middle and late stages rather than waiting until you’re thirsty. If you’ve nailed the bike fueling (90 g carbs, 600 mg sodium, ~500 ml fluid per hour), the run should feel like steady work instead of a sudden energy drop.
