Sir Chris Hoy made light work of his keirin round this morning as he began his bid for what would be an historic sixth Olympic gold medal.
He rode away from everyone except for New Zealand's Simon Van Velthooven. The Kiwi knew Hoy's wheel was the one to be on, and followed him when he made his move with one-and-a-half laps to go.
As Hoy accelerated again through the bell the pair went clear. When they crossed the line the four riders behind were ten bike lengths back and spread all over the track.
Germany's Maximilian Levy and France's Mickael Bourgain won the next two heats, both of which finished will all six riders bunched closely together.
Hoy's clear win was an ominous sign for the other nations, especially the French who were left stunned by Jason Kenny's win in the sprint yesterday. Gregory Bauge, the man he beat, was so frustrated by the Kenny's 2-0 victory that he started asking Kenny questions in the press conference as the gathered journalists looked on.
Bauge was favourite to win yesterday's sprint, but lost to Kenny who, like in Beijing, produced his peak performance on the day it mattered. Hoy is favourite for the keirin and should he, like Kenny, hit a four year peak this afternoon it would take a miracle to beat him. And the other nations know it.
Sarah Hammer of America was fastest in the individual pursuit to take a one point lead after four rounds of the women's omnium. Hammer, a former individual pursuit world champion beat Laura Trott by one second. Trott was second, beating the times of Tara Whitten of Canada (who had beaten her in the IP at the world championships) and Annette Edmondson of Australia.
Trott is the favourite to win the 500m time trial final event, meaning the others must try to beat her in the scratch race. Whitten and Edmondson must also hope some of the lesser ranked riders take up the places between them and Trott and Hammer.
This is not easy to do. Both Whitten and Edmondson need to make up seven points on Trott and eight on Hammer just to draw level, and there are only 18 riders in the field. The only tactic for both Whitten and Edmondson is to try and force a slow race that allows riders low down the rankings to gain a lap, and then to get a lap themselves in the final stages. All the time hoping Trott and Hammer don't gain the lap.
Meanwhile, Hammer and Trott will be watching each other, while also making sure Whitten and Edmondson don't escape.
In total, three medals will be decided tonight on the track, and British riders are in contention for all three. The third event is the women's sprint, which will be Victoria Pendleton's last ever race. If she can stand on the podium tonight it will make for an emotional finale to her cycling career that started when she was just nine years old.
