The organizers said 17 men, including former Calvin Klein cover model Marcus Schenkenberg, and 13 women, including porn star Mia Magma, slid down the mountainside in Braunlage Saturday for the fourth-annual event, The Local reported Monday.
The participants were required by safety rules to wear helmets, shoes and underwear, but were otherwise unclothed when they took their turns sledding.
"With a lot of German beer and Jagermeister, I'll be able to keep myself warm," Schenkenberg said.
A 37-year-old Hannover man was declared the winner of the event and was awarded $1,300.
