With support from Great British Racing, keen to push this success story, Doyle has been on a whirlwind round of interviews – from BBC Radio 5 live to Sky Sports, who sponsor her.
It is all a far cry from her spell on the sidelines after being kicked under the chin by a horse following a fall at Haydock, when she smashed most of her teeth and accidentally swallowed some of them when she came round.
Doyle had £8,000 worth of dental work at the firm owned by jockey Sam Waley-Cohen, where they X-rayed her jaw, removed four roots and fitted dentures and caps.
She is a regular at Oaksey House near her home in Lambourn, Berkshire, where riders recover from injuries in a state-of-the-art facility provided by the Injured Jockeys’ Fund.
“It was an expensive injury, but you are not going to ride horses without risks and that’s what I do every day,” she says.
“At the start of this year my aim was to just have a clear run of things and I have, touch wood, until now, which has made a hell of a difference.”
You suspect that Doyle and Marquand drive each other on, although they insist there is no burning rivalry between them on the track.
“They have an incredible, healthy, energetic, sporting lifestyle, which works well for them,” says Perham.
“The new version of riders we are training are all infatuated with fitness. The older generation are fit jockeys but the younger generation are looking at this in a slightly different way.”
