He was born with cystic fibrosis, a chronic progressive disease characterized by a thick, sticky mucous that clogs the lungs. Each day, he takes 50-70 pills. And he hooks himself up to a machine called the vest that shakes his upper body for 1-1.5 hours a day to loosen the mucus from his lungs. All this – – so he can run. He’s run 6 marathons, five of which have been under 4 hours. Why does he do it?
“I do it because I want to prove to myself that I can…I run because one day I might not able to.”
