It is the dance craze that has brought thousands on their feet and now the zumba world record is being attempted in Norwich.

Sallie-Anne Sadler has organised the mammoth 12-hour dance event on June 12 at Riverside's Project nightclub to raise money for the East Anglian Air Ambulance.

Sessions will run continuously from 8am until 8pm and dancers are encouraged to sign up for slots of half an hour at a time.

Mrs Sadler, 37, of The Avenue, Horning, is joined by guest instructors from across East Anglia to help run the classes.

She said: 'I was the second qualified zumba instructor in Norwich. I tried it after one of the girls I worked with said I would love it.

'I left my job organising exercise and fitness courses at Norfolk County Council to start teaching. I now teach 12 classes every week.'

Mrs Sadler is supported by her husband, Vinny, a sales manager and their two daughters Leanne, 15, and Anna, 14.

She said: 'Anna loves zumba and will be taking part in the world record attempt with her friends.

'I am scheduled to teach for three and a half hours on the day. I won't be able to walk the next day.

'I wanted to do a really long class for charity. Someone suggested a world record attempt. It's good to bring people together.'

In just one day, her Facebook page for the event attracted 350 fans and 120 dance slots have already been booked.

'I am hoping to raise thousands. Dancers pay �5 per half hour class and some people have already set up Just Giving pages online. Project donated the venue and the instructors are donating their time free of charge.

'It's a good charity to support. Some of my instructors are from all over Norfolk and Cambridgeshire so it is a charity which everyone can relate to.'

Mrs Sadler will give all the proceeds to the charity.

'I would urge people to try it. They only have to dance for 30 minutes. People will have fun and should bring along friends to help us bring the world record to Norwich. Offices can bring teams of people to dance.' She said.
