Mark Carles is a runner, brother, son, and one of the bravest athletes we have had on the show. Given a few months to live over a year ago and he is still fighting the rare form of liver cancer he was diagnosed with by running and being with family. Matching tattoos with his mom, late nights and early mornings with his brother and even some kind words from Dan Rather will have you rethinking what you should get out of every day. Enjoy the show.
