Walkers are welcome in all events. All walkers start their race in the last corral behind the runners.

To register as a walker in either the Scotiabank Ottawa Marathon or Scotiabank Half Marathon races register in the WALK Division for your event.

For those planning to walk any other race, register for your event. When asked to select expected finish time – select the one that includes “Walkers”. Those planning to do a combination of walking and running should not select the Walker Division. Walkers should note the following time limits apply: 10k – 2 Hours, 1/2 Marathon – 4 Hours and Marathon – 7 Hours. These times limits will be strictly enforced and people who do not meet the time limits will be asked to move onto the sidewalk.
