Laurie recounts the first time he ever encountered David Berkoff at the Olympic Games. The closest thing he’s ever seen to a fish, Laurie says. Best known for his powerful underwater start, the eponymous “Berkoff Blastoff”. He completes almost half of the 100m backstroke underwater, taking only a few breaths throughout the race. David is a remarkable man with high aspirations. Olympic champion, and former world record-holder in two events. Berkoff was a backstroke specialist who won a total of four Olympic medals during his career at two different Olympic Games.
