IRONMAN 70.3 Nelson Mandela Bay

Arrive early and get a short, focused warm-up in the water so your first strokes are smooth. Seed yourself based on your swim pace so you’re not fighting for clear space for the first few hundred meters. In the first minutes, settle quickly into a steady cadence and breathing rhythm, keeping your head calm and your start pressure controlled so you don’t burn energy before the turn(s).

You’ll swim 1900 m in water that’s typically wetsuit legal (around 20.2°C, with the official call confirmed on race morning). Expect variable choppiness with a moderate south wind; keep your body streamlined and use consistent effort rather than reacting to every bump. Aim to breathe regularly and keep your line tidy—if you drift, correct early with small course changes instead of big sculling efforts. Fueling during the swim isn’t typically part of the plan; prioritize having everything ready for a smooth, quick transition so you can start your bike fueling on time.

Plan a clean T1: cap/goggles off, shoes on efficiently, and get your nutrition bottles and kit where you can access them fast. As you mount, accelerate gently for the first few minutes to find your rhythm, then lock into your target power/effort on the rolling terrain. If it’s choppy, keep your hands quiet and your pedaling smooth rather than chasing speed immediately after the mount.

Ride 92.9 km with 532 m of rolling elevation, which means you’ll feel repeated small efforts—stay composed and don’t spike power on the first rise. With wind at about 7.9 m/s from the S, expect cross/headwind stretches that can make your speed swing; ride the effort you can hold, and let the speed vary. Hydration and carbs are central here: target 90 g carbs per hour plus 1000 mg sodium per hour, and take in about 800 ml fluid per hour to stay ahead of the “moderate heat” creep. Because the course is rolling, set a fueling cadence that matches your ability to take sips/gels during flatter sections—don’t wait until you’re too spun up on the climbs; instead, take your planned intakes steadily and regularly throughout the ride.

In T2, focus on transition mechanics: rack your bike calmly, get your shoes on, and take the first 1–2 minutes easy to let your legs find the new rhythm. Your job off the bike is to feel “ready to run,” not to sprint—especially with the heat at a moderate level. As you start, shorten your first steps slightly and get your breathing under control before you build.

Run 21.1 km on a flat/fast course with only 66 m of elevation gain—this is where pacing discipline matters more than climbing ability. With air temperatures ranging roughly from 18.9°C to 25.8°C and a moderate heat feel, start the run feeling slightly conservative and build gradually once your form settles. Continue fueling aggressively but methodically: use your planned carbs target (90 g/hour), keep sodium at 1000 mg/hour, and maintain fluid intake (800 ml/hour) to match the day’s warmth and sweat rate. The wind on the run can still be noticeable—if you hit exposed stretches, prevent “feeling good” from turning into surging; keep effort steady and let the flat course reward your consistency.
