Anyone who has ever tried to surf knows its hard enough trying to stay on the board, but Panamanian surfing champion Gary Saavedra really pushed the endurance envelope when he rode a single wave for three hours and 55 minutes. In total, Saavedra surfed the wave for a total distance of 41.3 miles.
The Guinness Book of World Records achievement was accomplished with the help of a power boat, which Saavadera surfed behind across the Panama Canal. It may seem like an unfair advantage, but the act is still physically tough and mentally exhausting. The last wave rider who tried such a stunt only pulled it off for a little over an hour.
