Hertfordshire's Olympic champion cyclist Laura Trott has helped to launch the cycling equivalent of the London Marathon alongside London Mayor Boris Johnson.
The double gold medal winner has helped launch an annual cycling event weekend for London which will include a 100-mile "Marathon" bike ride.
The Ride London event will be held for the first time next year.
"This will be a great way of getting people involved with cycling," said Trott, who took gold in the cycling team pursuit and omnium.
Trott has "owned up" to dating fellow double Olympic gold medal winning cyclist Jason Kenny, 24.
Mr Johnson, announcing the new cycling event in Westminster, joked that Trott and Kenny, adding their medals together, were 16th in the world Olympic medal table.
Two more of the region's athletes start their Olympic campaign today.
Laura Trott of Harlow, goes in the heats of the women's team pursuit, while Milton Keynes athlete Greg Rutherford bids to qualify for the final of the men's long jump.
