Canada's largest marathon runs Oct 18, 2026 along Lake Ontario past the CN Tower. A fast, flat, certified Boston-qualifying course with a 6-hour limit and an Elite Label field.

Why attend here

Come for the flat, fast course along the lakeshore, and stay for Toronto in October—when the city's autumn colours peak in Queen's Park and the Distillery District's cobblestone lanes are perfect for a post-race stroll. Fuel up on a peameal bacon sandwich at the St. Lawrence Market, then warm up with a craft beer at a King West brewpub while the CN Tower glows over the skyline.

Course

Fast and flat point-to-point through downtown and along the Lake Ontario shoreline, with a steeper rise and fall over the Spadina flyover mid-course and a gentle Bay Street climb in the closing kilometres toward Nathan Phillips Square; net elevation change is still minimal.
