British Cycling performance director Sir Dave Brailsford has quit his role.

The 50-year-old joined the organisation in 2003 and has been credited with Great Britain’s success at the 2008 and 2012 Olympics.

Brailsford holds a similar position with pro-cycling outfit Team Sky and missed last month’s Track Cycling World Championships to focus on that role.

As he had previously hinted he might, Brailsford is set to focus on his duties at Team Sky, the men’s professional offshoot of the Olympic squad which has won the last two Tours de France with Sir Bradley Wiggins and Chris Froome.

Brailsford originally joined British Cycling in 1997 not long after Lottery funding began, initially because of his links with the cycle trade, but assuming greater responsibility under the then head Peter Keen before taking over as Performance Director when Keen moved on in 2003.
