Georgia Tame produced a winning start for Great Britain on day three of the Equerry Bolesworth International Horse Show.
Sussex rider Georgia triumphed in the AC Jackson-sponsored four-star class against the clock, leading a clean sweep of the top five places by British riders.
Graham Babes and Glencoe had set the pace, clocking 60.90 seconds, but Georgia steered eight-year-old chestnut mare 27 Canya Dance home in a time of 59.74 seconds to take spot.
"She is a really fast horse, and I saw Graham, who went just before me, really gallop. His horse has a big stride," Georgia said.
"My horse doesn't have such a big stride, so I had to keep it quite tight.
"I was quick over the first fence, and then really tight around to two, which was where she probably made up the time on Graham. It would certainly be her speciality type of class."
Georgia has been based at Irish star Shane Breen's facility for the last four-and-a-half years, and she has no doubt about the influence he has had on her riding career.
"He is such an amazing rider," she added. "Just watching him, you learn so much.
"It has been a good season for me so far. We started off competing in Dubai, and had a couple of other trips abroad, and I love it at Bolesworth.
"I competed here last year, and it is such a great show. I am really looking forward to the next few days."
Chloe Aston and Flavie van de Helle took third place in 60.94 seconds, with Jess Dimmock and Billy Fleance finishing fourth and Louise Saywell guiding Feigtling home in fifth spot.
