MORE than 100 naked roller coaster riders are set to scream their way to a new World Record this weekend.

The thrill-seekers will be shedding their inhibitions, and clothes, for the “ultimate white nipple ride” to raise money for breast cancer.

The bare-cheeked fun is set to take place at Adventure Island in Southend with the rude riders hopping on to the Green Scream Rollercoaster.

It is hoped the efforts will smash the existing record of 32, set back in 2004 at Alton Towers.

Sunday morning’s fun also has a serious side as the riders will be raising vital funds and awareness for Southend Hospital Charitable Foundation’s Bosom Pals Appeal which needs �750,000 to bring state of the art imaging and diagnostic equipment to the hospital’s breast care unit.

Anyone wanting to put their bits on the line for charity, the gates open at 9am for registration, with the naked rollercoaster rides taking place from about 9.30am onwards.
