LONDON, May 17 (Xinhua) -- It has been described as London's "cheekiest challenge," with people flocking on Wednesday to sign up for a fund-raising fun run through the capital's famous zoo, where participants will be required to be completely naked in the Streak for Tigers challenge.
The event is returning to London Zoo on Aug. 10, after a successful inaugural event last year.
Playing with the collective noun for a group of Sumatran tigers, Streak for Tigers will raise money to protect tigers and their habitats around the world.
London Zoo's resident Sumatran tigers, Jae Jae and Melati, are playing an important role in the international conservation breeding program for the species.
"Their cubs will go on to create their own families and help to inspire millions more people to help save this critically-endangered species," said the zoo spokeswoman.
