Running 26-point-2 miles would be hard enough.
But imagine doing it while dribbling a basketball....even two basketballs.
Darren Weissman finished a marathon in south Florida, dribbling two balls for the full four and a half hours.
Darren is a personal trainer and motivational speaker known as Doctor Dribble.
He did the race to raise money for an organization that helps foster kids.
Doctor Dribble says he was in pain after the race, but it was worth it.
