Jason Kenny set an Olympic record of 9.713s in the men's sprint qualifying this morning.
Backed by a noisy crowd at the London Velodrome, Kenny averaged more than 74kph in the race.
French triple world champion Gregory Bauge was second, ahead of Australian Shane Perkins and German Robert Foerstemann, who finished third and fourth respectively.
The qualifying lap is used to seed the riders, who will race in the 1/16 final match later on Saturday.
With 17 riders at the start of the competition, Kenny is therefore granted a bye into the 1/8 finals.
