Warning: Partial nudity below.

A GROUP of thrillseekers have taken their love of roller-coasters to new extremes.

The daring bunch of 57 people stripped off together for a naked ride on the Green Scream rollercoaster at the Adventure Island theme park in the UK on the weekend, in a bid to set a new world record.

While they didn’t break the record — which was set in 2010 where 102 people rode the same rollercoaster in the buff — they didn’t mind as it was all in the name of charity.

They managed to raise more than $21,000 for the Southend Hospital Charitable Foundation’s Keyhole Cancer Appeal.

“We’ve heard some amazing stories from so many who have been directly, or indirectly, affected by cancer and wanted to give something back,” Adventure Island spokesman Andrew Renton told the UK’s Mirror,

“I am really proud Adventure Island could offer them this opportunity. Admittedly it would have been nice to have bettered our record — but we are still the World Record holders at the end of the day.”

Southend Hospital Charitable Foundation praised those who took part for their bravery.

“It takes a lot of nerve to take off all your clothes in front of complete strangers, plus the world’s media,” spokeswoman Lucy Thomas-Clayton said.

“We would like to say a massive thank you to everyone who was brave enough to bare all and raise such a huge amount of cash for our vitally important cause.”
