Olympic silver medallist Emma Pooley has announced she will retire from cycling after she competes for England in Sunday's road race at the Glasgow 2014 Commonwealth Games.

The 31-year-old London-born rider, who won a time-trial silver medal at the Beijing Olympics in 2008 after helping Nicole Cooke to road-race gold, made the announcement on the Rouleur cycling website on Tuesday morning.

The 2010 world road time-trial champion told Rouleur: "You have to go sometime. I considered retiring after the London Olympics, but I didn't feel like I was ready.

"I've been mulling it over, and came to the conclusion that the Commonwealth Games is the perfect opportunity - it's a big event, it's almost at home, and I want to go out properly, when I've planned it and have no regrets."
