04·Race-Day Execution

Controlled aggression, start to finish

Weather & cooling

August in Ottawa is often hot and highly humid, with temperatures reaching 27°C or higher. Utilize every aid station for ice and cold water to douse your head and body, keeping your core temperature down from the start of the run.

Fuel & hydration

Aim for 80-100g of carbohydrates and 750-1000ml of fluids per hour on the bike to counter the high sweat rates caused by humidity. Increase sodium intake to prevent cramping, especially if you are a heavy sweater.

Pacing

On a flat bike course, the temptation is to over-torque early; stick strictly to your target power and avoid burning matches. Save your legs for the run, where the flat concrete pathways will punish any early pacing mistakes.

Gear & logistics

Choose a deep-section front wheel and a rear disc wheel to maximize aerodynamic efficiency on the flat parkway. Bring both tinted and clear goggles to accommodate changing morning light conditions over Britannia Beach.

Frequently Asked Questions

What is the water temperature for the IRONMAN Canada-Ottawa swim?

The water temperature in the Ottawa River during early August typically ranges from 21°C to 24°C (70°F to 75°F). This means the 3.8-kilometer swim is highly likely to be wetsuit-optional for age-group athletes. You should prepare your pacing for potentially warm water conditions while enjoying the calm, protected waters of the river.

How hard is the IRONMAN Canada-Ottawa bike course?

The 180-kilometer bike course in Ottawa is flat to gently rolling, making it a very fast and aerodynamics-focused ride. You will cycle along the scenic, closed-to-traffic Colonel By Drive and adjacent parkways, which feature excellent road surfaces and minimal technical climbing. Your main challenges will be maintaining a consistent aerodynamic posture and managing potential crosswinds along the river corridors.

What is the run course like for IRONMAN Canada-Ottawa?

The 42.2-kilometer run course is exceptionally flat, spectator-friendly, and winds through the heart of Canada's capital city. You will run along the historic Rideau Canal and pass iconic landmarks like Parliament Hill on a multi-loop layout. Because the course offers virtually no elevation change, you can lock into a highly consistent, rhythm-based pacing strategy from start to finish.

What weather should I expect for IRONMAN Canada-Ottawa on August 2?

Ottawa in early August features warm summer weather, with average daytime highs ranging from 25°C to 28°C (77°F to 82°F) and high humidity levels. Overnight lows typically drop to around 15°C (59°F), meaning you will start the race in comfortable temperatures before the midday heat sets in. A robust hydration and electrolyte plan is essential to combat the summer heat and humidity during the run.
