After showing promise with two golds, a silver and a bronze at the 2007 European Youth Olympic Festival, Aimee Willmott won her first British Champs medal with 400m Individual Medley bronze in 2009 then went on to win silver in both individual medley events at the European Junior Championships in Prague.
She made the step up to senior international swimming the following season, competing at the 2010 European Championships in Budapest before making finals in both individual medleys and the 800m Freestyle for England at the Commonwealth Games in Delhi.
After finishing her school studies during a quiet 2011, Willmott burst back on to the scene at the 2012 British Gas Swimming Championships in London, clocking an English record to win silver in the 400m Individual Medley and qualify for her debut Olympics.
She finished 11th in the 400m IM at London 2012, competing on the same day as her father Stuart Willmott when he finished 15th in the 400m IM at the 1984 Olympics in Los Angeles.
Willmott won her first major medal with 800m Freestyle bronze at the 2012 European Short Course Championships then showed her freestyle improvement by adding 400m Freestyle bronze to her 400m Individual Medley silver at the 2013 British Gas Swimming Championships.
She competed at her World Championship debut later in 2013, finishing ninth in the 400m Individual Medley.
