Ottawa Race Weekend

Join thousands of runners from around the world

The prestigious Ottawa Marathon – Canada’s largest marathon – attracts some of the best athletes from all corners of the globe and thousands of spectators who cheer them on along the scenic route. Each year, close to 50,000 runners participate in the six official races: marathon, half marathon, 10K, 5K, 2K and kid’s marathon. Participants have raised millions of dollars through the Scotiabank Charity Challenge since it began in 2003.
