James Guy has medalled at every major benchmark meet since his senior international debut at the 2013 World Championships - including relay and individual golds at separate Worlds.
Guy swam the butterfly leg as part of the Men's 4x100m Medley Relay team that stunned the USA to secure victory in the event in Gwangju in 2019, four years on from his 200m Freestyle and 4x200m Freestyle Relay triumphs in Kazan.
The 2018 Commonwealth Games on Australia's Gold Coast - his second outing for Team England - saw Guy claim five medals, including four silvers - three in the relays and one in the Men's 100m Butterfly - and a 400m Freestyle bronze.
He then went on to pick up four more medals at the Glasgow 2018 European Championships, three of them relay golds and an individual bronze in the 100m Butterfly. He narrowly missed out on a podium finish in the 200m Freestyle, ranking fourth overall.
An action-packed schedule at the 2017 World Championships in Budapest saw Guy medal in three of the six events in which he competed.
An individual bronze came his way in the Men's 100m Butterfly, where he broke an eight-year-old British record twice on the way to his podium finish. Guy also helped Britain successfully defend the Men's 4x200m Freestyle world title - an effort which brought a new British record with it - and, on the final night of racing in Budapest, he collected silver as part of the Men's 4x100m Medley Relay quartet, swimming the butterfly leg.
At Rio 2016, Guy claimed two silver medals on his Olympic debut. They came in the Men's 4x200m Freestyle and 4x100m Medley relays, both in British record time. The National Centre Bath athlete also competed individually in the 200m and 400m Freestyle events, securing finals berths in both and finishing fourth and sixth respectively.
Earlier in 2016, he secured the Men's 4x100 Medley Relay title at the European Championships, along with an individual continental bronze in the 200m Freestyle.
Guy truly showed his potential at the 2015 World Championships in Kazan by winning a breathtaking individual gold in the Men's 200m Freestyle, followed up by a silver in the 400m Freestyle. He then achieved gold for a second time at the Worlds when he anchored the Men's 4x200m Freestyle Relay quartet to a historic victory and on to the top of the podium.
In 2014, the Bury-born swimmer laid down a signal of intent with a hat-trick of golds at the British Championships, taking the touch in the 200m Freestyle, 400m Freestyle and 200m Butterfly events - and breaking the British Men's 400m Freestyle record in the process.
He won his first senior international medal later in the season, lowering the British record again to claim 400m Freestyle bronze for England on his Commonwealth debut at Glasgow 2014.
The previous year saw Guy make his mark among the senior ranks of British Swimming when he made it on to the podium at the British Championships, sealing himself a bronze in both the 200m and 400m Freestyle events.
