Skinny dippers from across England joined together at a beach in Druridge Bay at sunrise Saturday and ran into the sea, the CNN reported.
Dubbed the North East Skinny Dip, organizers hoped to set Guinness World Record, as well as raise money for the mental health charity, Mind.
Although organizers said they likely failed at their attempt to set the record, the event was a success nonetheless, the Sunday Sun reported.
"Loads of us ran naked into the sea to raise money for Mind and to celebrate ourselves and our bodies," said organizer Jacqueline Higginson, 34. "I did a skinny dip last year where we broke the world record, I don't think there was enough to do it today but there was enough of us for it to be a lot of fun."
Higginson said the event raised more than $3,000.
"We think we have reached our target of 2,000 pounds ($3,249) but donations are still flooding in so hopefully it will be more than this," she said.
