The hosts have now won eight medals, including their first two golds for rowers Heather Stanning and Helen Glover and road cyclist Bradley Wiggins - who has now won seven Olympic medals, one more than Sir Steve Redgrave.
It means they have won eight medals in total - two golds, two silvers and four bronzes - meaning they are ahead of the pace they set in Beijing with swimmer Michael Jamieson quickest into tonight's 200m breaststroke final.
At this stage of the Beijing Games, where Team GB finished fourth on the medal table and won 47 medals, they'd claimed seven podium places.
"With four medals, including two gold, in a single afternoon, Team GB is now in full stride," said Team GB chef de mission Hunt.
"Heather Stanning, Helen Glover and Bradley Wiggins have written their very own unique and wonderful chapters in the storied history of British Olympic sport this afternoon.
"To become the first British gold medallists in women’s rowing is an accomplishment that will stand the test of time, and our congratulations go out to Heather, Helen and everyone at British rowing.
"The bronze medal won this afternoon by the men’s eight in rowing is an illustration of the talent and depth that exists throughout the British rowing team. "Equally, Bradley Wiggins has cemented his position as one of the greatest British Olympians ever.
"To claim an Olympic gold medal and the Tour de France in the span of less than four weeks is nothing short of extraordinary.
"As with rowing, the bronze medal won by Chris Froome shows the outstanding work being done by British Cycling to develop world-class athletes throughout the programme."
