IRONMAN 70.3 Calgary

Get used to the texture of the water early—do a gradual warm-up if you can, then focus on controlled, repeatable strokes. Seed yourself to match your swim pace so you’re not forced to sprint for clear water in the first minutes. At the gun, commit to your plan: settle into rhythm quickly, stay calm when the first turns get crowded, and avoid over-bulling in the initial surge.

You’ll cover 1,899 m of freshwater where conditions (including temperature) can vary—so keep your effort smooth rather than trying to “power through” discomfort. Use the wind only indirectly for the swim: most of the impact will show up later on the bike and run, but in the water you’ll want a steady body position to limit unnecessary drag. With the field spreading, find clean lines as soon as you can and use sighting to stay on course. Fueling on the swim is not the focus—plan to be ready to start taking fluids right away once you’re on the bike.

Your T1 is about turning the swim legs into smooth bike rhythm. Once you rack your bike, secure your shoes and get moving without rushing—then drink or take a quick sip if your setup allows. As you mount, immediately find a cadence you can hold on rolling terrain; don’t surge out hard while you’re still transitioning. Over the first few minutes, set your effort around steady power/effort and start taking in your first planned drink and carbs.

The bike is 87.7 km with 413 m of elevation gain on a rolling profile, so expect repeated minor climbs and descents that can tempt you to spike power. With wind at 4.5 m/s from the W, watch how it changes your speed and effort: hold steady on crosswind/into-wind sections by trusting your pacing rather than chasing numbers. Fueling is built for consistency—aim for 90 g carbs, 750 mg sodium, and 650 ml fluid per hour, distributed in regular intervals instead of big hits. Start sipping early, keep hydration steady, and use the rolling nature to take “easy calories” on the flats and downhills while staying safe and smooth in descents.

In T2, the goal is to regain coordination quickly without stomping. Transition through the “first 1–2 minutes” by starting slightly controlled and letting your stride come back—rolling terrain can make the first push feel harder than it should. As you start the run, take a moment to set your breathing cadence and aim for even effort rather than chasing early pace. Have your fueling plan ready so you can begin taking carbs and fluids as soon as the routine supports it.

You’ll run 21.1 km with 146 m of elevation gain on a rolling course that rewards rhythm and patience. With moderate heat (air temps ranging 11.5–24.1 C), manage effort early so you don’t overshoot before the warmest parts—small hills can quickly shift your perceived exertion. Wind from the W can impact exposed stretches: if you feel yourself burning up into the wind, shorten the stride a touch and stay composed instead of launching harder. Keep taking in carbs and fluid according to your plan—maintain steady hydration and intake so your energy doesn’t lag on the mid-to-late sections.
