Romero, 31, made history at the Beijing Games when she won cycling’s individual pursuit title, just four years after claiming silver in Athens in the sport of rowing.
However, she has not competed for Great Britain since and, after her event was dropped from the London 2012 programme, her future looked even more in doubt.
Romero had hinted that she may move to the road to contest the time trial – finishing fourth at this year’s British Championships – with Wendy Houvenaghel, Jo Rowsell, Dani King, Laura Trott and Paralympian Sarah Storey all ahead of her in the pecking order for the three-person team pursuit squad.
â€œHaving suffered several setbacks at crucial points, I believe Iâ€™m no longer on a pathway which will see me fulfil my Olympic ambition to win a second Olympic gold medal,” she admitted.
“Iâ€™m proud to have contributed to the cycling teamâ€™s great Olympic triumph in Beijing and I thank all the amazing people within British Cycling who were central to my success. I wish my current team mates every success in London next year.”
British Cycling performance manager Shane Hutton hailed the decision as a ‘great loss to the team’ but remains determined to stay upbeat with the women’s team pursuit squad looking one of the strongest medal hopes, following this year’s world title performance in Apeldoorn.
He said: “Itâ€™s a shame to lose an Olympic Champion going into the Olympic year but looking ahead, we have some great young talent in addition to experienced riders in the team pursuit squad.
“Iâ€™m confident we can remain on track to hit our performance targets in the lead up to and during the London Olympic Games.â€
