Ben Ainslie is great ambassador for his sport and Britain, says fellow Olympic hero Sir Chris Hoy "Ben is very focused on his sport, for him it's not about being a celebrity, and that has to be admired," said Hoy, one of two British Olympians who have topped Ainslie's record of four gold medals. Sir Steve Redgrave is the other. Hoy, speaking at the launch of his new range of bikes, also strongly supported Dave Brailsford's zero tolerance on past doping offenders at Team Sky introduced in the wake of the Lance Armstrong affair. "I am 100 per cent behind what Sky are doing and I find it frustrating that one of the few teams that are really trying to change the sport for the better is the one that is coming under such scrutiny," said Hoy. The Team Sky approach is the right approach and it's the same as the BOA [British Olympic Association] and their Olympic bylaw earlier this year [whereby an athlete with a previous drugs ban was excluded from the Olympics]. To me they are parallel cases. Instead of people penalising GB and the BOA for their approach, should the rest of the world not be following the BOA approach? We should always be looking for deterrents. You can't be relying on people's moral compasses, you have to have something to stop them doing it. Hoy flies to Perth on Monday for a three-week training block with the Great Britain track squad before testing his fitness at the Rotterdam six-day event in January, as he decides whether to continue racing through to the Commonwealth Games in Glasgow in 2014, when the track cycling events will be held in the Sir Chris Hoy velodrome.
