IRONMAN 70.3 Mont-Tremblant

Start with a simple warm-up: get a few minutes of easy strokes in before you line up, then do 4–6 short accelerations (10–15 seconds) so your cadence matches race pace. Seed yourself to avoid being kicked on the first stretch—go slightly more conservative than your ego says, because the first minutes are about positioning, not speed. For the first 50–150 meters, stay calm, find clean water, and settle into a smooth rhythm; if you’re sighting, do it early and consistent rather than every other minute.

You’re swimming 1950 m in variable freshwater conditions, so expect small changes in surface feel and possible choppiness depending on wind. The key is to lock into a controlled effort—rolling in intensity in the first third usually costs you by the time you’re settling into breathing and cadence. Because the wind is coming from the SW (4.2 m/s), you may notice it affecting nearby chop and buoy lines; keep your body position stable and let your stroke “track” through the water rather than overreaching. Fueling during the swim is generally unnecessary—save your carbs and fluids for the bike where you can absorb them reliably.

In T1, move efficiently: get your bike shoes staged correctly, dry/secure what needs securing, and transition quickly without racing your heart rate. As soon as you mount, establish rhythm immediately—first priority is smooth power and cadence rather than chasing speed. For the first 10–15 minutes on a rolling course, keep intensity controlled so the later climbs and descents don’t “bankrupt” your legs early.

This bike is 91.3 km with 787 m of rolling elevation, so think in terms of repeatable surges: push slightly on rises, recover on flatter sections, and stay composed through descents. With a SW wind around 4.2 m/s, you can get uneven effort—plan to ride steadier on exposed sections and avoid sprinting to match speed changes; let your power guide you over wind-driven speed swings. Your fueling target is 90 g carbs per hour plus 750 mg sodium and 650 ml fluid per hour—start early and stay consistent rather than trying to catch up later. Aim to drink regularly (not just at aid stations), and take carbs in the same cadence every lap/segment so your gut stays predictable across the rolling terrain.

In T2, focus on getting your feet under you fast: quick but not sloppy—walk only if you must, otherwise transition directly into running form. Off the bike, your first 1–3 minutes will feel heavy; keep steps slightly shorter and cadence a bit higher than you think to avoid overstriding. Mentally set the first mile/first kilometers as “calibration”—you’re trying to find rhythm, not prove fitness immediately.

The run is 21.2 km with 80 m of rolling elevation, so it’s easy to fluctuate pace even if the climbs are not long. With moderate heat (air temperature spanning 12.9–22.6°C), start controlled and let your pace build only if you’re staying on top of hydration. Your key performance lever is heat management and sodium: keep fluid intake consistent and don’t wait for thirst, especially if the sun increases after the cool start. Since the bike fueling was 90 g carbs/hr, the run should be supported by the carbs strategy you carried through the race plan; use the aid stations to stay on schedule rather than making up large gaps when you feel slow.
