A WORLD record was smashed by a Huddersfield school – on the fields where the late Record Breakers host Roy Castle once played.

Almost 1,000 pupils and 100 teachers from Honley High School took part in the world’s largest aerobic weight training session.

Castle, the Scholes-born entertainer who went on to present the TV programme Record Breakers, was a pupil at the school when it was known as Holme Valley Grammar School.

Huddersfield Giants Star Jamie Simpson joined Hour of Power instructor Rajko Radovic to help motivate the participants.

At 2pm, a sea of students in their red PE kits covered the playing fields while willing staff joined in from the sidelines.

Australian star Jamie, who has played only five matches this season due to a shoulder injury, said: “It was great to see so many people getting involved and it was a lot of fun.

“The club approached me and asked me about getting involved. I thought it was a great cause and really worth it.

“I am trying to get fit before the Superleague Grand Final so it was a good work-out too.”

Each participant was issued with two water bottles and used them as half-kilogram weights.

They were bought from One Water, One Difference, a charity which donates 100% of its profits to helping those suffering from the drought in Africa.

The event was put together by assistant head-teacher Paul Sharrock and art teacher Graham Wheatcroft.

Graham met Rajko at Loughborough University and was trained by him six years ago to become a resistance instructor.

He also instructs the Hour of Power in various Huddersfield locations during his spare time.

He said: “It took two months to plan this entire event.

“We hope to be the biggest event. There was a school in London that did a smaller event. I think they managed to get 750 pupils, but it was an unofficial record.

“My next ambition is to get all senior schools in Kirklees involved and hold an event at the Galpharm Stadium, but that will take a lot longer to organise.”

Rajko, who’s father founded Hour of Power, came from London to take part in the event.

He said: “It’s one of the few classes that everyone can get involved in. We have young pupils to a 62-year-old staff member.

“It was encouraging to see that many children exercising and even better to see those who wouldn’t normally get involved join in too.

“A world record would be fantastic, but I won’t believe it ’till I see it in writing.

“The benefit of One Water is that the children are also not drinking heavily sugar-laden drinks and are continuing to be healthy.”
