Dick and Rick Hoyt are a father-and-son team from Massachusetts who together compete just about continuously in marathon races. If
they're not in a marathon they are in a triathlon.
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.
