Terry Fox
In October 1979, Fox wrote a letter to the Canadian Cancer Society. He told them about what he wanted to do. He asked them to give him money so he could start the run. He told them that he was going to finish the run, even if he had to "crawl every last mile". The Cancer Society did not know if he was going to finish the run, but they supported him once a doctor said that he was able to run. The left ventricle of Fox's heart was larger than normal. Doctors told Fox about the risks of the run. They did not think his heart was a problem. They supported his run when he told them he was going to stop running if he had heart problems.
