The tournament, in association with Sport Abroad and Zurich Premiership side Saracens RFC, attracted players from all over England – and a handful of teams from Wales.
Despite clashing with several major rugby events, Kris Chesney, the former England Sevens captain and current Saracens No.8, found time to drop in and sign autographs and be photographed with some of the tournament's young hopefuls.
Winner of the Under-13 NSRT National Trophy was Chinthurst School, Tadworth, Surrey, who beat off some of Britain's best to face stiff opposition from Thomas's School, Battersea, in the Final – a game in which they triumphed 6-0.
U12 winners were the team from St Bede's School, Eastbourne, who beat Crosfields, Reading 7-0, while the U11 Finalists Birchfield School, from Albrighton, Wolverhampton, and Chinthurst, Surrey, shared the honours following a 0-0 tie.

The National Prep Schools Rugby Tournament is acknowledged as the premier rugby event in the Prep Schools' sporting calendar and more than 500 pupils from schools all over the country took part in this year's Finals.
Stephen Borthwick, Headmaster of Epsom College, who presented the prizes said: "We were honoured and delighted to host both the Regional Festival and the National Finals of the Sport Abroad National Schools Rugby Tournament this year and to welcome pupils from all over the country to Epsom for the National Finals.
"It was a fantastic day, the weather was kind to us, and the atmosphere was superb. Congratulations must go to all teams who made it through to the Finals, but especially to those who won the title in their respective age group.
It was the first time the tournament had been officially held at Epsom College, although the school did step in at the eleventh hour in 2002 when the host school's rugby pitches proved unfit for play.
The Sport Abroad National Schools Rugby Tournament was founded eight years ago and has seen a steady growth in popularity every year. Organisers include former England and Lions player Roger Uttley MA OBE.
The tournament is a showcase for young talent of the future and several of the previous U13 winners have gone on to play for England, Wales and Scotland U18s, U19s and U21s at national level.
This year’s festival drew a record entry of 2,500 pupils from a total of 70 schools.
