The Ottawa Marathon is one of Canada's premier races, offering a fast, flat course through the nation's capital. The late May timing often coincides with the Canadian Tulip Festival, adding color to an already scenic course past Parliament Hill.

The Course

The course loops through Ottawa and across the river into Gatineau, Quebec, showcasing both English and French Canada. The terrain is remarkably flat, making it ideal for personal bests.

Capital Running

The course highlights Ottawa's landmarks:

  • Parliament Hill (Start/near Finish) - Canada's government center
  • Sussex Drive - Prime Minister's residence area
  • ByWard Market - Historic market district
  • Gatineau, Quebec - Cross-river into French Canada
  • Rideau Canal - UNESCO World Heritage waterway
  • Ottawa River Parkway - Scenic riverside running
  • Parliament Hill (Finish) - Grand governmental finale

Fast Canadian Running

Ottawa delivers speed:

  • Only 65m elevation gain - very flat
  • Cool late May temperatures
  • Excellent road surfaces
  • Boston qualifying race

Why Ottawa?

Ottawa offers a unique bilingual Canadian experience. Running past Parliament, crossing into Quebec, and finishing with views of the Peace Tower creates a distinctly Canadian marathon.

The Tulip Festival (when timing aligns) adds millions of tulips to the course - a gift from the Netherlands that Ottawa has cultivated since WWII.
