Sir Chris Hoy rode to glory as he took an historic fifth Olympic title on a golden day for Britain.
Sir Chris equalled Sir Steve Redgrave's record haul of five golds and boosted the atmosphere at the Velodrome where fans saw Victoria Pendleton and Jess Varnish miss out on a medal chance after being relegated from the team sprint event for a takeover infringement.
Sir Chris and team-mates Philip Hindes and Jason Kenny smashed the world record they set in qualifying as they successfully defended their title in the men's team sprint against France.
Their win topped off a fantastic day as Team GB shot up the medals table with sharp-shooter Peter Wilson gunning his way to Olympic glory and Etienne Stott and Tim Baillie triumphing in the two-man canoe slalom.
Britain won a second medal in the slalom with David Florence and Richard Hounslow clincing the silver.
Gemma Gibbons also took home a silver in the women's 78kg judo final, boosting the home nation's medal haul to five golds, six silver and four bronze.
The British lightweight men's four won a silver medal in a thrilling sprint for the line today, but their achievement in blustery conditions immediately sparked controversy at Eton Dorney.
Brothers Richard and Peter Chambers, Rob Williams and Chris Bartley were frustrated that world governing body FISA did not take the cross-wind into account and alter the racing lane order.
As a semi-final winner, Britain raced in lane three but the direction of the wind meant lanes five and six had the better conditions.
Williams admitted after the race that the "gnarly" conditions over the opening 1000 metres, before the grandstands, affected their performance.
