Jazz Carlin had a stellar 2016 season as she became Team GB's first double medallist of the Rio 2016 Games after taking silver in both the Women's 400m and 800m Freestyle.
During the return from her Rio 2018 break Jazz began the transition over to open water swimming attending a number of FINA Grand Prix events and competed in the Women's 10km at the Glasgow 2018 European Championships where she finished 14th.
Following time out of the pool in 2017, Carlin was back racing for Team Wales at Gold Coast 2018 with a sixth-place finish in the 800m Freestyle and fifth place finish as part of the Welsh relay quartet in the Women's 4x200m Freestyle Relay.
She returned domestic action at the British Swimming Championships where she secured gold in the 800m Freestyle to retain her title and she also came home with a silver and a bronze medal.
Her Olympic results mirrored those achieved at the LEN European Aquatics Championships in London earlier in 2016 as she again claimed continental silvers over the 400m and 800m Freestyle.
Three Domestic titles at the British Championships in London, 200m, 400m, and 800m Freestyle were all hers. She then headed out to her fourth World Championships in Russia where she took bronze in the 800m Freestyle.
Jazz hit top form in 2014, winning the Commonwealth, European and British titles over 800m Freestyle as well as European and British gold and Commonwealth silver in the 400m Freestyle, lowering her Welsh records over 200m, 400m and 800m Freestyle over the course of the season.
2013 was the comeback season for Jazz, bouncing back with a hat-trick of golds across 400m, 800m and 1500m Freestyle at the 2013 British Gas Swimming Championships then a fourth-place finish in the 400m Freestyle at the 2013 World Championships in Barcelona.
The combination of recurring tonsillitis and glandular fever disrupted her progress during the 2011 and 2012 seasons, preventing her from qualifying for her first Olympics.
Jazz's international breakthrough came in 2009 when she was selected for the World Championship team after two bronze medals and a silver at the British Swimming Championships in Sheffield. The Welsh swimmer immediately made her mark at the highest level, helping the British 4 x 200m Freestyle Relay quartet to bronze in Rome.
