IRONMAN 70.3 Türkiye

Arrive early, get your body quiet and warm, and do a short freshwater-specific warm-up (a few minutes of easy swimming plus a couple of controlled accelerations) so your first strokes feel organized. If you can choose a start position, seed based on your sustainable effort—your goal is to avoid sprinting for clear water in the first minutes. In the first 100–200 m, focus on smooth breathing and a straight, efficient line; don’t chase feet too aggressively until you’re settled behind or around your target pace group.

Swim is 2,035 m in freshwater where the temperature varies, so plan for a “controlled start” rather than going hard immediately. With typical conditions shifting between cooler and warmer air, expect your heart rate to rise if you start too fast—settle into a rhythm quickly and keep your stroke length efficient. Since the wind affects the surface more than the water itself, sighting and line-staying matter; aim for the shortest clean path to the next buoy and avoid unnecessary zig-zags. Fueling during the swim is usually minimal; prioritize hydration and take in your race fueling once you’re on the bike.

Plan a smooth swim-to-bike transition: move efficiently through the wetsuit/gear steps per your official race morning instructions, then get your shoes on and straighten your cadence as soon as the bike starts rolling. In the first minutes on the bike, gradually build to your target power/effort—don’t surge just because the legs feel okay. Stay composed through any congestion: keep your line predictable, and set up for fast, flat execution rather than braking or coasting unnecessarily.

Ride 90.2 km on a flat/fast profile with 84 m elevation gain—this is where steady power and clean aerodynamics will carry you. With wind from the N at about 3.6 m/s, you may feel slight headwind/tailwind phases; stay consistent and resist the urge to “fight” the wind—smooth effort is faster than reactive surges. Use the flat course to establish a sustainable rhythm and lock into fueling early, targeting 90 g carbs and 1,000 mg sodium per hour with about 800 ml fluid per hour. Take in carbs frequently rather than in big hits, and pair sips of fluid with sodium to reduce stomach strain as the temperature warms toward the upper end of the range.

During T2 (bike→run), expect your quads to feel immediate fatigue and your stride to feel slightly “heavy.” Start the run with a calm, shorter-stride cadence for the first few minutes—don’t try to force pace until your breathing settles and your feet find the rhythm. Do a quick check of form: relaxed shoulders, steady cadence, and smooth forward lean; this is a flat/fast 21.1 km, so efficient mechanics matter.

Run 21.1 km on a flat/fast profile with 19 m elevation gain, so the main challenge is usually maintaining intensity while heat remains moderate (air temps can be as high as 25°C). With wind around 3.6 m/s from the N, expect comfort to vary—on exposed segments you may feel cooler or more exposed; keep your effort steady rather than adjusting too aggressively. Continue fueling consistently based on your hour targets: 90 g carbs, 1,000 mg sodium, and about 800 ml fluid per hour (distributed through aid stations). If you start overheating or your stomach gets unsettled, slow down slightly and focus on small, frequent sips while maintaining sodium intake—staying hydrated helps you avoid the early-race “burn” from going out too hot.
