Georgia Tame continued an outstanding run of success at the Equerry Bolesworth International Horse Show by completing a title treble.
Georgia had already claimed her second victory of the week just four hours earlier in the International Arena's neighbouring Castle Arena.
But she was in no mood to stop there, adding the Horseware Ireland four-star 1.45metre speed class to her Bolesworth collection with eight-year-old mare Z7 Caretina.
The leaderboard changed hands late in the action, just when it looked as though long-time leaders - Sweden's Angelie von Essen and Cochella - might have done enough for victory.
Thirty six of the 40 starters had already gone, but Ellen Whitaker then made a concerted bid for the £7,300 top prize with Jack Van'T Kattenheye, clocking 68.75 seconds.
But Ellen's lead lasted barely as long as the round took her, as Georgia took more than a second off that time to claim another thrilling success.
Angelie had to settle for third, with another British combination - Louise Simpson and Felix X - taking fourth.
Georgia is based at Shane Breen's Sussex yard, and reflecting on her latest triumph, she said: "The mare is only eight, but she is so fast.
"I saw a few people go, and Ellen was just before me, and I thought we would need to gallop pretty fast if we were going to try and win, but she is quick enough.
"Shane advised me to keep it tight throughout the course and take strides out where you could. There was one line where you could go seven or eight strides, and he said to go eight, with half the course still to go.
"I think some went the seven strides there, and by the end of the course they were a bit flat.
"It has been a great week, definitely one of my best.
"I think this mare is probably going to jump bigger classes. She is a lot more ahead of the other one - Z7 Canya Dance. She has done a few rankings classes already, whereas the other one hasn't. We have had the both for just over two years now."
