Olympic rowing champion, turned America's Cup cyclor, Joe Sullivan has admitted to some unpleasant side effects of his power work in Bermuda.
As Team New Zealand prepare for the first-to-seven Cup match against Oracle Team USA, starting on Sunday morning, Sullivan and fellow former Olympian, sprint cyclist Simon van Velthooven have given an insight into what the cyclors go through during a race.
Both are well used to experiencing pain in the previous sporting careers. Even so it takes some managing.
Van Velthooven said Sullivan, double sculling gold medallist at the London Olympics of 2012 with Nathan Cohen, loses his sense of taste when he's driving himself hard during racing.
''You can lose your sight a bit towards the end and you definitely lose your hearing a little bit,'' Sullivan said.
