Championing LGBT rights and mental health in sport alongside his athletic career, Bosworth has spoken openly about both.[7]
Bosworth came out as gay on the BBC's Victoria Derbyshire show on 13 October 2015.[8] In the interview he explained that his family, friends and fellow sports athletes had known that he was gay for a number of years, and the coming out was to a wider audience to answer lingering questions from fans and to be himself. In the interview he told the BBC that he had been in "a really happy relationship" for the last four-and-a-half years.[9] He proposed to and was accepted by his now-fiancé, Harry Dineley on Copacabana Beach during the Rio Olympics.[10]
In publications by the BBC, SkySports[7] and the Telegraph among many others, Bosworth speaks about his mental health and how he overcame a period of depression. Alongside media appearances, he now also regularly visits schools and universities, to talk about his experiences as a professional athlete, LGBT equality, the importance of mental health and how sport can be of great benefit.
