Joanna Rowsell, Dani King and Laura Trott twice smashed the world record as they won the team pursuit gold at the Track Worlds.

Great Britain won a second team pursuit duel with Australia in two days at the Track Cycling World Championships as Joanna Rowsell, Dani King and Laura Trott set two world records at the Hisense Arena in Melbourne.
After the men triumphed on day one, Britain's women also improved their own world record entering the final competition before August's London Olympics track programme - but the 2.428-second improvement means they must now revise their Games goal after going faster sooner than anticipated.
Rowsell, King and Trott clocked three minutes 15.720 seconds to ensure Britain have now won four of the five titles since the three-kilometre event was incorporated into the World Championships programme in 2008.
Australia's Annette Edmondson, Melissa Hoskins and Josephine Tomic were second in 3mins 16.943secs, with Canada third ahead of New Zealand in an event which will make its Olympic debut in London.
The 21-year-old King and 19-year-old Trott now have two world titles from two attempts, while Rowsell, who missed out on selection in 2011 following illness and injury, is a three-time world champion after reclaiming the prized rainbow jersey she most recently won in 2009 in Pruszkow.
On top of the world
The 23-year-old Rowsell, from Cheam, said: "I can't believe I'm world champion again - it's been three years. I so badly wanted that rainbow jersey back.
"We're surprised how fast we've ridden here - we might need to adjust our targets now.
"We knew we were going to have to break the world record to win today - we didn't quite know how much by. (Three minutes) 15 (seconds) is great.
"We didn't think we'd see this time til August. We need to rethink a bit there."
Rowsell was reserve in Apeldoorn and believes Wendy Houvenaghel, the 37-year-old world champion from 2008, 2009 and 2011, remains in the selection mix ahead of London despite being a spectator this time.
"We're all going to keep getting faster and faster," added Rowsell, whose assertion was backed up by coach Paul Manning.
"I'm sure she'll stay with us and keep getting faster as well. Hopefully we'll be invincible by the Olympics."
Intense rivalry
The rivalry intensified in training prior to this week's racing as Britain and Australia each improved upon the world record of 3:18.148 set by Rowsell, King and Trott at February's London Track World Cup.
While Australia may have resorted to subterfuge to find out how Britain's men were training, British Cycling head coach Shane Sutton and his brother Gary, coach to Australia's women, merely shared the information.
Manning did not pass on the news on to his team, but they had guessed.
Trott said: "We had an inkling that they'd done something. Our coach was pushing the tenths (of a second). I was like: 'He's heard something we don't know'."
Australia were first to officially break the mark, clocking 3:17.053 in qualifying before Britain went faster still in 3:16.850 to set up the final decider.
As Britain started steadily, the hosts set the early pace in the final and led by almost 1.5 seconds before a phenomenal last kilometre - including a two-lap turn at the front from Trott - saw Britain win by 1.233secs.
Trott said: "We knew we had to go quicker after the London World Cup.
"We wanted to beat them on their home soil, especially before the Olympics. It puts out a strong message.
"They've
