Almost 600 students at St Mary's Grammar School in Belfast have successfully broken the record for the largest hurling training session in history.
An official representative was on hand from the Guinness Book of World Records to oversee 577 pupils complete the mass coaching session.
The school organised the event as part of an effort to celebrate hurling and to promote healthy living among the pupils at the west Belfast school.
The record break was backed by Allianz, local GAA coaches and other voluntary organisations.
Speaking about the effort, the school's principal John Martin said: "We are delighted to be officially recognised as Guinness World Record holders. This was a big logistical undertaking by the staff and the pupils who have prepared very well over the last two weeks.
"We also received support from the local community and the school family including the parents. St Mary’s is very much a part of the west Belfast community and today’s achievement is a reflection of that."
Glenn Pollard was present for the effort as the official adjudicator for Guinness World Records.
Praising the effort of the school he said: "A mass participation event like this one is a difficult and detailed undertaking. I travel the world on behalf of Guinness World Records to witness first hand record breaking attempts and I was very impressed at the efforts of the school today, including the staff and the pupils.
"They have earned this award and I am delighted to declare that St Mary’s is an official holder of a Guinness World Record."
