Running in Ottawa: A Seasonal Guide
Ottawa's humid continental climate shapes the running experience across all four seasons. Cold winters test even dedicated runners, but the payoff is spectacular fall and spring running seasons.
Peak season (May and June): These are the months where everything clicks: comfortable temperatures, manageable wind, and enough daylight for after-work runs.
Off-season strategy: Layer up and watch for wind chill in winter. The real danger is not cold air but exposed skin in wind. Run Window factors wind chill into every recommendation.
Local runners know that canal becomes a skating rink in winter. Also worth noting: summer festivals bring energy to the city.
