In 2011, an old school friend persuaded Bowen to try out a sitting volleyball team, the FSDW Celtic Dragons, based in Cardiff.[3] Bowen made a strong impression and in September 2011 was part of the Women's Great Britain team that competed in the EVCD (European Committee Volleyball for Disabled) European Championships in Rotterdam.[1] The team failed to win any of their games, finishing seventh. Bowen was then selected for the Women's Great Britain team to play in Cairo in the WOVD (World Organisation Volleyball for Disabled) Intercontinental Cup. Britain again finished bottom of their group.
Although not securing strong performances leading up to the games, as host nation, the Great Britain women's sitting volleyball team qualified for the 2012 Summer Paralympics, and Bowen was part of the 11 strong squad.[4] The British team lost all three of their Paralympic matches failing to progress to the knock-out stages, though Bowen had a good game against Japan, finishing as the team's top scorer.[1]
After the Paralympics Bowen was selected, along with Welsh Olympian Dai Greene, as the mystery runner in the annual Nos Galan road race.[5]
