T1 — swim to bike

Think transition flow as a sequence: set up your kit in T1 so your shoes and glasses are easy to grab, then move through without stopping to “rethink” anything. Off the swim, you want your legs to feel like they’re working, not flailing—start pedaling as soon as you mount, and keep the first minutes easy enough to let your heart rate settle. Once you’re up to speed, focus on smooth cadence and getting into your planned power before you chase anyone—rolling courses punish surging.

During the bike

The bike is 88.9km with 679m of rolling elevation, so expect repeated efforts where steadiness matters more than hero power. With a west wind (~4.3 m/s), crosswinds can show up on exposed sections—stay composed on the approach, keep a relaxed upper body, and don’t tense up when gusts hit. Fueling and hydration should match your targets: aim for about 90g carbs and 1000mg sodium per hour, supported by roughly 800ml fluid per hour, using the course’s normal access points to avoid falling behind. On the climbs, ride controlled—press smoothly into the hills without spiking power, and on descents keep your braking light and your line tidy so you can carry speed into the next roller without overheating your legs.

Closing notes

Your takeaway: treat the rolling profile as many controlled accelerations, not one big effort. If you keep power smoother than your feelings, the run will feel significantly better.
