Jess Varnish and Victoria Pendleton: Struck gold with a world record display
Great Britain's women reigned supreme at the Olympic Velodrome on the second day of the Track World Cup to provide a tantalising glimpse of what will be possible come the Games in August.
Jess Varnish and Victoria Pendleton won gold in a world record time in the team sprint, and Joanna Rowsell, Laura Trott and Dani King emulated the feat 30 minutes later in the team pursuit.
Sir Chris Hoy, Ross Edgar and Jason Kenny added bronze in the team sprint and have plenty of work to do if they are to overhaul Germany and France in Olympic competition, which takes place from August 2 to 7.
Both the women's events are new to the Olympic programme and the fall of the world records was not exactly a surprise.
Varnish and Pendleton put in arguably the performance of the evening, beating world champions and Olympic favourites Anna Meares and Kaarle McCulloch in the two-lap event, hours after the Australian duo had set a new world record in qualifying.
The British pair, silver medallists in the 2011 World Championships, recorded a national record of 32.966 seconds in their heat, before a scintillating world best of 32.754secs in the final secured gold.
Meares led Varnish by 0.232secs after the opening lap, but Pendleton overhauled McCulloch in the finale with a 13.962 split - the only rider to dip below 14 seconds.
Pendleton, who revealed the British duo had changed to a tougher gear for the final, said: "It was wonderful. To come to this track and do a time like that fills us with confidence.
"I feel we've got more to give, but if you're already at the top and have got more to give that's a good place to be."
The 6,000-capacity partisan crowd did not have long to wait to be sent further into raptures as the team pursuit squad backed up their status as world champions with victory in the three-kilometre event.
After Australia beat the United States' near two-year-old world record, taking third place in three minutes 19.164 seconds, Britain ensured the new mark lasted little more than a few minutes.
Rowsell, Trott and King clocked 3mins 18.148secs to win gold ahead of Canada, who also bettered the previous world best, finishing in 3:18.982.
Trott dug deep to keep the team together towards the end of the final, taking to the front for an extended one-and-a-half-lap stint.
The 19-year-old, who will this weekend ride in the omnium, said: "I knew as soon as those two went down to a half (a lap) I needed to do a longer turn. I just did it and hoped for the best.
"It just kept the pace there, kept the speed there. It was just the right thing to do.
"It shows how much we can work as a team and how much we trust each other."
Britain have won three of the four world titles on offer in the event and King was part of the squad which won last March.
However, she was omitted from the qualifying ride before replacing Wendy Houvenaghel for the final.
King said: "When I got told this morning I was going into the team I just thought, 'I can do this'. I'm absolutely ecstatic."
Rowsell admitted the roar of the home support caused her to start ahead of the prescribed time schedule in the heat, and was pleased with an improved display in the final.
She said: "We tried to go out a little bit steadier and really back up the ride, back up that last kilo. We delivered and broke the world record."
King anticipates the world record will continue to fall in the event.
She said: "It's going to come tumbling down. Tonight's just proved that. It's driving us on further."
There was another 'Ashes' battle in the men's team sprint, with Edgar, Kenny and Hoy clocking 43.781 to take bronze ahead of Australia. Germany triumphed in 43.562 with France second.
Hoy said: "We haven't really performed consistently in this event since Beijing. This is probably our quickest ride since 2009.
"When you look at what the Germans did to win the gold medal, I think we're only about a bike-length or so behind them."
Ben Swift was eighth overnight after three of six events in the men's omnium, while Matt Crampton was fourth in the non-Olympic one-kilometre time-trial.
Pendleton and Varnish will turn to individual action in the sprint tomorrow, Hoy and Crampton will ride in the Keirin and Rowsell in the non-Olympic individual pursuit.
Sir Chris Hoy rounded off the London Track World Cup in style by striking gold again in the men's sprint.
Gold medals for Sir Chris Hoy and Jo Rowsell were the GB highlights on a memorable day at the Track World Cup.
Jamie Staff says Jason Kenny should be GB's lead-off man in the team sprint.
