Thousands of runners across Canada are keeping the legacy of Terry Fox alive by running to raise money for cancer research Sunday.

The 33rd edition of the Terry Fox Run sees more than 9,000 such events being held across the country.

Terry Fox lost a limb to cancer, and with an artificial leg was running across Canada;   running the equivalent of a marathon every day.

He was forced to end his cross-country Marathon of Hope in Thunder Bay after his cancer spread to his lungs.

To date, the Terry Fox Foundation has raised more than $600 million for cancer research.
