"I felt stinging pain, it was a hard whack."
Karen Wiltshire had just been hit on the bottom with a whip by a rival jockey during a race.
After she dismounted from her horse, a trainer noticed a split in her riding breeches and observed: "They weren't made for women's backsides."
This was the 1970s and Wiltshire was trying to break new ground as a woman in what was then the male-dominated world of horse racing. Her ordeal was not over.
When she returned to the changing room at Warwick, another man riding in the same race jumped over a partition to sexually assault her.
"He's groping and trying to kiss me. Luckily, I'd done judo at an all-girls' convent school and fought him off," recalls Wiltshire.
Why did she carry on, and not complain?
"Times have completely changed since the 1970s, when you wouldn't be able to do much about it," she said.
"You didn't want to draw attention because it could affect your career. All I wanted to do was race so I just had to block that out."
She was overlooked for rides, verbally abused and ridiculed by other staff at her stables, but still went on to become the first professional jockey to ride a winner in British Flat racing when, aged 22, she guided The Goldstone to victory at Salisbury in 1978.
Her struggles against misogyny, prejudice and bullying are detailed in a new biography called 'No Place For a Girl'.
