Run for a Reason

Run for a Reason at Tamarack Ottawa Race Weekend and do it all in support of advancing patient care and research at The Ottawa Hospital.

What’s your reason to run?

Every step you take will help support world-class patient care and leading-edge research at The Ottawa Hospital. You can RUN or WALK to make sure every patient has access to the most advanced life-saving treatment when they need it most. It could be your father, sister, son, colleague, or friend.

Whether you register for the 2 km, 5 km, 10 km, half marathon, or marathon, you will be a part of Canada’s biggest marathon weekend. You will feel the energy and excitement of being a part of this exciting event. You can make it even more special by creating a team with work colleagues, family, or friends and run or walk together in support of The Ottawa Hospital. Just imagine that rush of crossing the finish line!

You’ll be creating a better tomorrow for health care in Ottawa.
