Harrow's Ciara McGrath, and fellow Harefield Gymnastics Academy teammates Katie Smith and Sophie Burfield, won the Junior Women's Group title at the recent British Acrobatic Gymnastics Championships in Stoke on Trent.
It was the third successive year that Ciara had taken the title.
Ciara and Katie, the European bronze medallists last October, teamed up with new partner Sophie Burfield to produce a polished performance, and their highest ever score.
The trio scored 28.95 out of 30 in their dynamic routine, the highest score of the whole competition, 27.5 in balance, and 28.35 in their combined routine to clinch the title.
Six other Harrow gymnasts also competed in the Championships for Harefield.
Canons High School student Hannah Feeney, competing with Grace Blacklock and Claire-Louise Thompson in the senior women's group, were only able to perform their balance routine because of Claire's broken finger, but scored a highly creditable 27.59. This was the second highest score in that routine, less than 0.7 behind the European Champions from Spelthorne.
In the junior mixed pairs, London Champions Matt Short and former St George's pupil Laura Noone, in their first British Championships, beat off a challenge from two experienced internationals to win silver with an excellent score of 27.65 in their combined routine.
In the junior women's pairs, former Sacred Heart student Kelly Mannion, and North London Collegiate's Deborah Owen, twice British Junior Champions, were outdone by tough competition in their last performance together and bowed out with a bronze, scoring 27.15. Rachael Prest and Marlborough pupil Poppy Spalding, London Regional Champions this year, scored 26.55 to take fourth place.
In the 11-16 women's pairs, Hatch End High student Rebecca Copas and Laura Jarrett showed their enormous promise by scoring 28.05 in the final, in a high-scoring round.
Normally a score over 28 would rate a medal, but this performance at least earned Becca and Laura a place in trials for the forthcoming World Championships.
