At just 21, Terry Fox set out to run across Canada — a marathon every day — on a prosthetic leg to raise money for cancer research.

Terry was determined to make a difference. Diagnosed with bone cancer at 18, he had already lost one of his legs, but he refused to let that stop him. With his heart set on raising awareness and funds, he began his journey from St. John’s, Newfoundland, on April 12, 1980. For 143 days, he ran through rain, snow, and scorching heat, covering a staggering 3,339 miles as the world watched in awe.

But cancer had other plans. The disease spread to his lungs, forcing him to stop just miles short of his goal. Despite his tireless spirit, Terry was forced to abandon his run on September 1, 1980. His mission, however, was far from over.

A year later, Terry Fox passed away at just 22, but his legacy continued to grow. Today, his Marathon of Hope has raised over $850 million for cancer research, and his courage has inspired millions of people around the world to run for those who can’t.

Terry Fox’s fight didn’t end with his death. His determination, spirit, and dedication to others continue to inspire generations, proving that even the shortest lives can leave the greatest legacies.
