Olympics cycling: Lizzie Armitstead wins road race silver

Lizzie Armitstead wins Britain's first medal of the 2012 Olympics as Netherlands' Marianne Vos claimed gold in the women's road race on Day Two.

Armitstead took silver with Russian Olga Zabelinskaya third in a thrilling rain-soaked race that ended in a sprint finish on The Mall in front of Buckingham Palace.

The trio formed a breakaway group and, in a sprint for the line, Vos had too much speed and power to win gold.
