Rebecca Adlington discusses impact of trolling in latest episode of Sky Sports Driving Force

As a double Olympic gold medallist from Beijing 2008 and a double Olympic bronze medallist from London 2012, Adlington is Britain's most successful swimmer.

After her two gold medals in Beijing, she was awarded an OBE in the 2009 New Year Honours list and despite retiring from swimming in 2013, she remains one of Britain's most high-profile and well-known swimmers.

However, after enjoying great success, the swimmer had to deal with a most unpleasant side of modern-day life, and something that remains a reality for so many athletes and individuals in the public eye.
