IRONMAN 70.3 Zell am See-Kaprun

Arrive early, get your bearings in the freshwater, and start your warm-up before the field builds. Aim to be seeded with swimmers of similar pace so your first 100–200 m isn’t spent fighting for clear water. In the first few minutes, settle into a controlled breathing rhythm and keep your effort smooth—save the “fast” strokes for when you have open lanes.

You’ll cover 1899 m in freshwater where the temperature can vary, so start slightly conservative and let your body “find” the right feel. With typical offshore/near-lake conditions, focus on efficient pacing: don’t surge early just because the pack is moving. Every time you pass a reference point, mentally smooth your stroke rate and keep kicks/submerged effort consistent to avoid burning energy you’ll need later. Fueling during the swim isn’t the priority—focus on getting to T1 calm, composed, and ready to drink and start your bike fueling plan immediately.

Plan for a fast, orderly T1: transition from a controlled swim pace to a purposeful bike mount, rack and gear check quickly, then get your first pedal strokes in as soon as you’re stable. Before you really push, do a quick “systems check” on cadence, gear choice, and your hydration bottle presence. Mentally commit to pacing your first climbs—this course’s hilly 902 m gain punishes early overexertion more than late.

The bike is 89.4 km with 902 m of climbing on a hilly profile, so think in terms of effort management: ride hard on steady segments, but don’t let surges on climbs become unplanned intervals. With wind described as 2 m/s from the N, you’ll likely feel small changes in resistance and stability—stay smooth on the bars, especially when the road turns expose you to cross/headwind segments. Fuel early and consistently: target 90 g carbs per hour, 750 mg sodium per hour, and about 650 ml fluid per hour. On climbs, keep the cadence in a sustainable range and continue drinking even if your breathing rises—small sips prevent a fueling gap that costs you on the run.

T2 is where you turn bike load into running rhythm. Spend a moment getting your form: first steps should feel light and upright, not like a brake-then-accelerate sprint. Expect your legs to feel heavy early—focus on a smooth cadence, relaxed shoulders, and breathing that settles within the first few kilometers. Immediately before/at the start of the run, be ready to take fluids consistent with your fueling rhythm from the bike.

You’ll run 21.5 km with 42 m of elevation gain on a flat/fast profile, so the main challenge is holding power and preventing the early adrenaline from turning into too-fast minutes. With moderate heat conditions (air temps ranging from 13.1°C to 22.8°C), manage your perceived effort: if you feel you’re breathing too hard early, dial pace back by a small amount rather than “trying to survive.” Hydration and intake should follow what you set on the bike—keep taking fluids as offered to prevent overheating and to maintain stomach comfort. Since the elevation is low, your pacing win is consistency: aim to gradually build or maintain rather than spike early, and protect your pace in the middle third so you have something left late.
