T1 — swim to bike

Think “disassemble, mount, accelerate”: when you hit T1, keep it efficient—rack/unrack quickly, hydrate if needed, and get shoes on with minimal fuss. Once mounted (without rushing the first seconds), spin easy for a minute to get the legs warm, then start building toward your target power/effort. Use the flat/fast 90.3 km profile to lock in rhythm; don’t go hard just because the course feels easy. Since wind is coming from the E at about 4 m/s, plan to stay steady and slightly more aerodynamic when you feel cross/tail components.

During the bike

Ride 90.3 km on a flat/fast course with 202 m of elevation gain—this is where consistency beats spikes. With wind from the E at about 4 m/s, expect brief moments where you’ll feel more drag or a calmer push; stay smooth through those changes and keep power stable. Aim to hit your fueling target of 90 g carbs per hour, 750 mg sodium per hour, and about 650 ml fluid per hour—split it across the ride so you’re never waiting until you’re behind. If you’re on schedule, you’ll protect the run; if you’re not, adjust before the mid-to-late part of the bike so you don’t “chase” calories too late. Hydrate early and regularly—moderate heat means thirst can lag behind sweat needs, so use your intake plan rather than guessing.

Closing notes

As you approach the dismount area, gradually reduce effort for a controlled off-ramp—not a sudden slowdown—so your legs feel prepared for T2. Make sure you’ve got your last planned drink/carb in before the final stretch, then focus on a clean, fast T2 entry rather than cranking the last minutes.
