About Scotiabank Ottawa Half Marathon

The Scotiabank Ottawa Half-Marathon is the weekend’s biggest field. The course is fast and relatively flat, making it great for personal bests and runners trying the distance for the first time. The course takes runners past historic landmarks, through vibrant neighbourhoods and across the Ottawa river through the province of Quebec.
