Jamaica's world record holder Usain Bolt says it will take the perfect race to win the 100 metres final at the Beijing Olympics.
Bolt, who will run both the 100 and 200 in Beijing, admitted he "blew people's minds" in May when he set a new world mark of 9.72 seconds in one of his few professional outings at the shorter distance.
The Jamaican, who sees the 200 as his main event, is likely to be up against compatriot and former record holder Asafa Powell and world champion Tyson Gay in the 100 final on August 16.
The perfect race for Bolt would certainly include a good start, particularly in the 100 where his height gives him a disadvantage over more compact runners.
Bolt says he rates winning an Olympic gold medal higher than breaking a world record and he wants to become the first man to win both sprint golds since Carl Lewis in Los Angeles in 1984.
