World champion Peter Sagan won his eighth Tour de France stage despite a technical glitch on the uphill finish to the third stage in Longwy yesterday. Sagan's foot came unclipped from his pedal as he started to accelerate at the finish, but he kept his calm and still proved too strong for the competition at the end of the 212.5km run from Verviers in Belgium.
