He lost a leg to cancer as a child yet went on to become a 3-time paralympian

Mark Barr was obsessed with sports as boy until he was diagnosed with bone cancer at the age of 14. The cancer was in his knee and spreading.

After a year of chemotherapy, doctors told Barr that if he wanted to survive, his right leg would have to be amputated. Barr was devastated until he met a nurse who was an amputee herself. She introduced him to the Paralympics.

When he is off training, Barr helps other amputees

He went on to not only beat his battle with cancer, but also become a three-time paralympian, competing in the Athens, Beijing, and Rio de Janeiro summer Olympics.

In 2018, Barr has set his sights on the Aramco Houston Half Marathon with Team Catapult, an American NGO that helps physically disabled people excel at endurance sports.

When he is not training, Barr inspires patients as a full-time trauma nurse. He says that he can never forget the bond he developed with the nurses who cared for him and wants to do the same for others.
