Why did terry start his marathon?

Answer 1

The best answer I read was from a friend of his, "anger" is what motivated Terry Fox. After his cancer was found, he spent a lot of time in a pediatric cancer ward & became friends with other patients. The majority of them died and he became determined to do something about this. The irony is that to-day, the type of bone cancer that cost him his leg and then his life, has a high cure rate.
