The Canadian and "Romeo" bested a three-horse jump-off to win their third U25 competition of the week at Thunderbird Show Park.

Competition is underway at Thunderbird in Langley, BC, and last year's series champion wasted no time picking up where she left off.

Highlights from Thursday's 1.40m Challenge, MarBill Hill U25 and Canadian Hunter Derby at Thunderbird Show Park.

Jaimie Ackerman and Driek win Friday's 1.45m; Kassidy Keith and Fenelon WF take Saturday's $5,000 MarBill Hill U25 class.

Competition continues at the Summer Fort Classic CSI3* with Irish rider Robert Blanchette placing one-two in the $25,000 Hunter Derby.
