Father-Son bond of Dick and Rick Hoyt

Wow, I'm just speechless about this video. Instead of me trying to explain this team, I'll quote their history here: "Dick and Rick Hoyt are a father-and-son team from Massachusetts who together compete just about continuously in marathon races. And if they’re not in a marathon they are in a triathlon — that daunting, almost superhuman, combination of 26.2 miles of running, 112 miles of bicycling, and 2.4 miles of swimming. Together they have climbed mountains, and once trekked 3,735 miles across America. It’s a remarkable record of exertion — all the more so when you consider that Rick can't walk or talk." For the rest of their history is here and their website here.
