Last Friday night saw boys and girls from different communities across Belfast pack down at Ulster's famous home ground to beat the previous record of 750, which was set by Milton Keynes scouts at Wembley Stadium in December last year.

Congratulations to all involved in setting the new world record including the students themselves, the teachers and coaches and especially Chris McCarey, who is head of rugby at Belfast Royal Academy.
The money raised will help to raise funds for the school's 'tour of a lifetime' to South Africa this summer, as well as supporting charities Tygerburg Children's Hospital, Newforge Taggers and the IRFU Charitable Trust.
