T1 — swim to bike

Think “transitions first”: as you come out of the water, get calm and spend a few seconds checking your kit—shoes on, helmet secured, any pre-bike drink within reach, and everything where you want it. During T1, keep it efficient: hydrate, rack smart, and remount quickly without rushing your setup. In the first minutes of the bike, build gradually—settle into a steady cadence and breathing before you lock in your target power/speed.

During the bike

The bike is 90.8 km with about 163 m of total elevation—flat/fast—so it’s built for consistent, efficient output rather than big surges. With wind around 4.5 m/s from the W, expect a noticeable cross/head component at times; keep your aero position stable and make smooth steering corrections so you don’t lose power fighting the bike. Fuel and drink to the planned rate: target 90 g carbs per hour, 750 mg sodium per hour, and 650 ml fluid per hour, taking it consistently rather than waiting for thirst. On a flat course, it’s easy to ride too “hot” early—stay disciplined, then keep the rhythm strong through the middle and late sections so the run comes out feeling controlled.

Closing notes

Your key bike job is staying steady in the wind and hitting the full fueling plan—this is what protects your 21.2 km run.
