James Guy made his full senior international debut at the 2013 World Championships in Barcelona and has medalled at every major benchmark meet since, including medals most recently at the 2016 Olympics and 2017 World Championships.
An action packed schedule in Budapest for James Guy saw him compete in six events and medal in three. An individual bronze came 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 that saw a new British record set and on the final night of racing in Budapest, he collected silver as part of the Men's 4x100m Medley Relay quartet.
In Rio Guy claimed two medals with silver in both the Men's 4x200m Freestyle and 4x100m Medley relays, both in British record time. James also competed individually in the 200m and 400m Freestyle events where he secured finals berths and finished fourth and seventh respectively.
The double Olympic silver medallist impressed the home crowd at the 2017 British Swimming Championships by winning four gold medals and securing his place on the plane to Budapest.
Earlier in 2016 he secured the Men's 4x100 Medley Relay European title along with an individual continental bronze in the 200m Freestyle.
James (England) showed his real potential at the 2015 World Championships by winning a breathtaking individual gold in the Men's 200m Freestyle, followed up by a silver in the 400m Freestyle. He achieved gold for a second time in Kazan, sensationally anchoring the 4x200m freestyle relay to a historic gold medal and onto the top of the podium.
The 2015 season also saw him claim two British titles at the London Aquatics Centre in the 200m and 400m Freestyle event.
In 2014, James laid down a signal of intent with a hat-trick of golds at the British Swimming Championships, taking the touch in the 200m Freestye, 400m Freestyle and 200m Butterfly, and breaking the British record in the 400m Freestyle.
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.
2013 was the year that 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 bronze in both the 200m and 400m Freestyle events.
He followed that up with double gold (200m Freestyle, 4x200m Freestyle) at his second European Junior Championships in Poznan, then made his senior international debut at the World Championships in Barcelona.
James made a positive international debut at the 2012 European Junior Championships in Antwerp, Belgium, taking bronze in the 400m Freestyle.
