Dick Hoyt, 67, and his son Rick, 46, have accomplished more than many of us could imagine. They've climbed mountains, completed 224 triathlons (including six Ironmans), 66 marathons, a 45-day cross-country bike ride, and more. Obviously, that's inspiring in and of itself.

What makes it AMAZING is that Rick is a quadriplegic and cannot walk or talk -- he was born with cerebral palsy, which kept him from ever being able to control his muscles and limbs, including his vocal chords.

Dick started participating in races and endurance events with his son when Rick was just 11, and the duo hasn't taken more than two weeks off since. Dick continues to train and compete because Rick gets so much joy out of it, and it makes him happy to see his son happy.
