Terry Fox pushed himself to run just one more light pole. He never physically finished his goal of running across Canada, however millions are running around the world in 40+ countries supporting a cause because of him. He could never of dreamed this kind of outcome or legacy for himself. Not bad for a guy wanting to run just one more light pole and set out to raise $1 million for cancer research. To date, $450 million has been raised in his name worldwide, along with being bestowed the companion of the order of Canada, along with 32 streets and several schools named after him, and many other honours.
If that is not heroic then I am not certain what is.
May your legacy live on Terry.
