Welsh swimmer Jazz has won multiple medals on the World, Commonwealth, European and British stage but it is her silver double at the Rio 2016 Olympic Games that is perhaps her finest career moment to date.
Four years after missing out on London 2012 through illness, Jazz was the only Team GB swimmer to win two individual medals in Brazil as she finished runner-up to the outstanding Katie Ledecky in both the 400m and 800m freestyle.
Jazz raced for Wales at the 2006 Commonwealth Games in Melbourne as a 15-year-old, then won her first World Championships medal – a 4x200m freestyle relay bronze – on her competition debut in 2009.
Silver and bronze medals followed at the Delhi 2010 Commonwealth Games before bouts of tonsillitis and glandular fever ended her hopes of competing at London 2012. Jazz fought back to full fitness, though, and became the first Welsh woman in 40 years to win Commonwealth Games gold when she took the 800m freestyle title at Glasgow 2014, along with 400m freestyle silver. She then claimed gold in both events at the European Championships before moving to Bath.
The 2015 season saw Jazz win her first individual World Championships medal, bronze in the 800m freestyle, and she went on to secure double silver at the 2016 European Championships – a feat she famously repeated in Rio later that summer.
After trying her hand at open-water swimming in 2017, Jazz will return to the pool in 2018 after being selected for her fourth Commonwealth Games with Wales.
