Calum Jarvis first represented Great Britain in 2012 and then went on to win silver at the Commonwealth Games before forming part of the successful 4x200m Freestyle relay team that won gold at the World Championships last summer.
He sealed his place at the World Championships after winning
bronze in the 200m Freestyle at the 2017 British Swimming Championships.
Jarvis (Wales) made an impact at his first World championships by helping the British quartet to gold in the men’s 4x200m Freestyle relay, stealing the title from the USA. 2015 also saw Jarvis claim his second career British title in the 100m Freestyle at the London Aquatics Centre.
Jarvis qualified for his debut Commonwealth Games at the 2014 British Championships in Glasgow, impressing to set a Welsh record for fourth in the 100m Freestyle and winning his second British medal with silver over 200m Freestyle. He sprung a surprise to land 200m Freestyle bronze at Glasgow 2014, breaking David Davies' welsh record in the final to seal his first senior international medal.
After a debut senior international appearance for Great Britain at the 2012 European Short Course Championships in Chartres, more finals spots secured at the 2013 edition of the British Championships, finishing sixth over 200m Freestyle and fifth over 200m Backstroke.
At the London 2012 Olympic Trials at the Aquatics Centre, Jarvis landed his first British title, setting a personal best for gold in the 200m Backstroke but narrowly missing the qualification time to swim at the Olympics.
Back in 2010 Calum Jarvis made his national breakthrough as a backstroke swimmer, finishing fifth over 200m Backstroke at the British Champs then improving to fourth in Manchester the following season.
