Britain enjoyed a golden afternoon in Rio after kayaker Joe Clarke and diving duo Jack Laugher and Chris Mears triumphed on and in the water.
After the agony of David Florence's last-placed finish a day earlier, Britain's Clarke lit up a gloomy Whitewater Stadium with the race of his life in the K1 canoe slalom final on Wednesday.
Clarke not only won Britain's first Olympic medal in the men's K1 since Campbell Walsh at Athens 2004 but secured gold in a time of 88.53 seconds.
A jubilant Clarke was stunned by his success.
"I just can't really put it into words," he said. "I'm just so made up. I have so many amazing memories of this sport and this just tops all of them in one day."
Clarke's gold was just Britain's second of the games after Adam Peaty's victory in the pool last Sunday, but within hours Team GB were celebrating an historic third as Laugher and Mears won on the synchronised 3m springboard.
The pair claimed Britain's first ever diving gold at an Olympics, adding the title to their European and Commonwealth gongs.
The result caps an incredible personal journey for Mears, who in 2009 was given just a five percent chance of survival after rupturing his spleen.
