Matthew Walker has one of the best records of any GB swimmer at major international competitions, having won medals at every Paralympics, IPC World Championship and IPC European Championship at which he has competed.
After winning S7 50m Freestyle gold at the 1998 IPC World Championships, he made his Paralympic debut at Sydney 2000, reaching the top spot of the podium with the 34pt 4x100m Freestyle Relay team as well as helping himself to S7 50m Freestyle silver and SB7 100m Breaststroke bronze.
Walker won eight more medals across the 2002 and 2006 Worlds and 2004 Paralympics before securing his best Paralympic haul at the 2008 Games in Beijing, walking away with four individual medals as well as 34pt 4x100m Freestyle gold for the third successive Games.
He went on a golden streak after Beijing, winning four golds at the 2009 Europeans then S7 50m Free gold at the 2010 Worlds and 2011 Europeans.
In between his recent world titles, Walker won an emotional bronze in the S7 50m Freestyle in front of a home crowd at London 2012, just three months after his father passed away.
Walker was back on top of the world rankings in 2013, defending his S7 50m Freestyle title at the World Championships in Montreal, before winning a hat-trick of silvers at his sixth European Championships in Eindhoven in 2014.
