Sir Bradley Wiggins reveals he was sexually groomed by a coach at the age of 13

The 2012 Tour de France winner and five-time Olympic gold medallist said he did not feel he could speak up at the time due to a difficult relationship with his stepfather.

Asked if he was groomed sexually, Wiggins added: "Yes. It all impacted me as an adult...I buried it. My stepfather was quite violent to me, he used to call me a f****t for wearing Lycra and stuff, so I didn't think I could tell him.

"I was such a loner... I just wanted to get out of the environment. I became so insular. I was quite a strange teenager in many ways and I think the drive on the bike stemmed from adversity."
