Adam Peaty storms to Team GB's first Rio 2016 gold in new world record

Uttoxeter's Adam Peaty sensationally won Britain's first medal of the 2016 Rio Olympics by taking gold in the men's 100 metres breaststroke and setting a new world record.

The 21-year-old, who trains in Derby, stormed to victory in 57.13 seconds, smashing his own world record for the second time in two days to scoop Britain's first men's swimming gold in decades.

As the historic victory sank in he proclaimed:

Peaty dominated his first Olympic final, beating second-place South African swimmer Cameron van der Burgh by a body length and slicing nearly half a second off the world record mark he set in qualifying.

The spellbinding swim was followed just minutes later with glory for Team GB's Jazz Carlin, who took silver in the women's 400 metres freestyle.

Describing the historic moment as "crazy" and "so surreal", the seemingly unflappable Peaty said he took the first 50 metres "easy" before bursting back along the home straight "with everything I've got".

Giving a thumbs up as he received his medal, the patriotic champion smiled ear-to-ear and - in contrast to many victorious Olympians - sang the national anthem before waving to his family in the crowds.

It was the culmination of seven years of training for the City of Derby swimmer, who said a pep talk from head of British Swimming, Bill Furniss, to "burn the boats, move forward and attack" helped him to shrug off the huge anticipation surrounding his bid.

It is the first men's Olympic gold by a British swimmer in 28 years, since Adrian Moorhouse's success in the same event in Seoul 1988.

A surprise star of Peaty's story has been his adoring grandmother, Mavis Williams, who roared him on in the early hours of Monday morning from her home in Sheffield.

Tweeting her congratulations to the winner and his coach, Melanie Marshall, she wrote: "Well you have done it @adam--peaty you have made it, your hard work paid off. Congratulations to you and @massivemel. So proud love Nan x."

Cheering him on from the poolside were his mother and father, Caroline and Mark Peaty, and girlfriend Anna Zair.

Mrs Peaty said she was "ecstatic", while a hoarse Mr Peaty appeared lost for words.
