Ottawa’s calendar spans a large amalgamated city—from ByWard Market and Lansdowne to Hog’s Back, City Hall, Tunney’s Pasture, Wesley Clover Parks, and outer starts in Manotick and Cumberland. Major road weekends (including Tamarack Ottawa Race Weekend) sit beside community, charity, and trail options; Gatineau races are a separate municipality.

Practical answers for planning from this list — not a generic city guide.
Ottawa and Gatineau sit close together but are different cities in different provinces. The directory may surface nearby options, so check the city shown on each card when you want a race on a particular side of the river.
Ottawa is a large amalgamated city, so starts in Kanata, Barrhaven, Manotick, Cumberland, Dunrobin, and other Ottawa communities can belong here. The listing should still name the actual venue or community because race-day travel can vary considerably across the city.
Ottawa combines major road-racing weekends with local community events, fundraising runs, and trail options. That makes it possible to choose between a large goal event and a smaller local race without leaving the city’s calendar.
Not always. Some events welcome walkers, teams, families, or fundraising participants alongside runners. Read the individual event details to understand whether it is a timed race, walk, relay, or another community format.
For events elsewhere in the province, browse races in Ontario. If you are considering Gatineau or another Quebec start, use the Quebec race calendar and check the listed venue before making travel plans.
