Usain Bolt has negotiated a series of delays and a false start in his own race before easily winning his quarter-final of the 100m at Jamaica's national championships.
Although sluggish from the blocks, the world record holder separated from the field after 40metres before cruising across the line in 10 point one five seconds.
However the six-time Olympic gold medallist was upset at the amount of time he had to wait before getting to run after a succession of false starts in other races.
Bolt says the whole system bothers him and he was out there too long.
