Sophie Wicks delivered an assured display to win the 128cms Pony Grand Prix at the Equerry Bolesworth International Horse Show.
The 12-year-old Cumbrian rider was in commanding jump-off form on Camizion, clocking 36.32 seconds after six combinations made it through from round one.
Leicestershire's Tabitha Kyle was chasing a Bolesworth double after landing the 138cms title on Saturday, but she had to be content with third place.
Tabitha, riding Living the Dream, recorded the quickest time, but one fence down proved expensive, with Izabella Rogers and Whitney Lass taking second spot by emulating Sophie and recording a double clear.
"It was a very good jump-off," said Sophie, following the Pony Parents-sponsored class..
"I have had the pony since October 2017, and this would be one of our biggest wins. It means so much to me to win here in the International Arena.
"It's quite a long way for us to travel anywhere for shows, but it's really worth it when you have a win like this one."
