Participants run in the 11th Terry Fox Marathon of Hope in Havana March 21, 2009. The marathon is held annually to raise funds for cancer research and to honor Canadian Terry Fox, who was diagnosed with cancer at the age of 18 in 1977. With his right leg partially amputated, Fox started to run a marathon every day across Canada, completing 5,373 km (3,339 miles), until he was forced to stop as the cancer had spread to his lungs. Fox died at the age of 22.
