IRONMAN 70.3 Geelong

Get to the start area early so you can settle, warm up calmly, and verify your seeding/position. In the first few minutes, focus on finding clear water with good sightlines and a controlled cadence rather than sprinting your strokes. If you’re between packs, choose a position that matches your sustainable pace—being a little conservative at the start helps your swim rhythm for the final third.

You’ll cover 1.958 km in water that’s typical for wetsuit-legal conditions (confirm the final ruling on race morning in the official IRONMAN athlete guide). With 21.1°C water, plan to swim “comfortable-hard” and keep your technique consistent—don’t let early traffic cause extra speed or wasted breathing. The south wind and cooler air can make the swim feel more variable when you surface and sight, so breathe regularly and use stable landmarks to avoid wandering. Fueling during the swim isn’t the priority; think of this leg as your opportunity to set up an efficient transition and a smooth start to the bike.

Your T1 plan should be simple: secure goggles/cap, rack and grab in a practiced order, then start pedaling without lingering. As you enter the bike, begin with a smooth ramp-up—first power/effort is often too high because excitement carries over. Keep your cadence comfortable and let the wind and traffic settle before you commit to your steady nutrition and pacing.

The course is 90.3 km and flat/fast with 336 m of elevation gain, so it rewards even pacing and disciplined effort. With a 6.1 m/s south wind, expect it to influence your effort more than the climbing does—when the wind hits, you’ll feel drag and speed can drop, so focus on holding your target output rather than chasing numbers on the bars. Over the flatter sections, keep your bike handling smooth and avoid sudden surges; on faster stretches, stay patient and let the wind do what it does. Fuel by targeting 90 g carbs per hour, 750 mg sodium per hour, and 650 ml fluid per hour—start early and stay consistent so you don’t fall behind as the bike progresses. Use aid stations to take in fluid and sodium reliably; if you’re thirsty later, you’re usually already behind.

T2 is where legs either feel connected or they feel heavy—aim to dismount and transition quickly, then start the run with a “controlled easy” first 1–2 km. Your first steps should feel springy but not fast; check your breathing and settle into a repeatable rhythm. Mentally, plan to start by regulating effort while your calves and hips adapt to the rolling terrain.

You’ll run 21.5 km with 81 m of elevation gain on a rolling profile, so you’ll feel small changes in grade more than dramatic climbs. Moderate heat plus a steady south wind can create a rhythm where you feel okay early, then heat and dehydration sneak up—stay disciplined with effort and water intake. Because the bike is flat/fast, the run can feel deceptively controllable at first; the key is to avoid turning the first rollers into surges. Keep your cadence smooth on uphills and avoid braking too hard on downhills—let the terrain guide you while you maintain your target pace. Continue fueling and hydration from your race plan; maintain your intake consistency so your energy doesn’t drop off in the middle third where rolling terrain often starts to sting.
