IRONMAN Canada-Ottawa

Arrive ready to move quickly in transition from swim into wetsuit/gear check and onto the bike prep. Get into the water early enough to settle your breathing and sighting—because the temperature varies, start by warming up progressively rather than going all-out immediately. In the first minutes after the start, line up where your pace matches the current pack, settle into a calm stroke, and focus on staying streamlined while you find clear lanes.

You’re racing 3809m in freshwater where the temperature varies, so your body will feel different at different phases of the swim—stay patient through the early minutes and let your rhythm come to you. The key in this environment is consistent breathing and repeatable sighting so you don’t drift as you pass different sections and recover from minor surges. If conditions create chop or slight current effects, keep your stroke rate stable and avoid overreaching—save the “big effort” for when you’re moving cleanly and efficiently. Fueling is generally not the main focus during the swim; focus on exiting in control, then execute your planned drink/sodium strategy immediately after you’re on the bike.

Think T1-to-bike flow as: get off the swim cleanly, keep your timing tight while you change shoes/gear, and remount smoothly with a controlled cadence. Don’t sprint out of T1—your legs will feel “heavy” after the swim, so aim for an easy spin for the first segment before you settle into your target bike effort. Take a moment in the first few minutes to verify your hydration access and bottle order so you’re not fumbling later when speed and focus rise.

Your bike is 179.7km with 458m of elevation gain and a flat/fast profile—this invites strong pacing, but it also makes it easy to go too hard early. With wind at 3.8 m/s from the W, expect stretches where you’ll feel either a headwind push or a tailwind ease; your power should stay steady even when the effort “feels” different, using controlled breathing and consistent cadence to stay on plan. Heat is moderate (air temps roughly 17.1–26.1C), so start hydrating early and keep sipping rather than waiting until you feel thirsty. Hit your fueling targets on the bike: 90g carbs per hour, 1000mg sodium per hour, and about 800 ml fluid per hour—use the bottles/gels you trained with and keep the intake consistent through the mid-to-late portions as fatigue ramps.

Plan your T2 with the expectation that your legs won’t feel springy right away after 179.7km of riding. Keep the first kilometers intentionally controlled—think “smooth and quick feet,” not “race pace immediately.” As you start moving, settle your stride length and focus on posture; the first part of the run should feel like a transition from bike rhythm into a sustainable run cadence. Hydration access should be ready so you can take fluids right when you’re supposed to—don’t wait until you’re already behind.

The run is 42.2km and the profile is listed as unknown here, so treat it as a pacing challenge rather than a “terrain guessing game.” With moderate heat and air temperatures roughly 17.1–26.1C, manage your effort by feel: if you’re getting hot, back off slightly early rather than paying for it later. Because wind is present (3.8 m/s from the W), expect some sections to feel tougher depending on direction—use steady breathing and cadence to prevent surging when you get a tailwind. Keep taking fluids on schedule and prioritize even pacing through the middle third so you can build late rather than fade—your fueling plan from the bike should carry forward into the run execution even if your appetite drops.
