Mcfly - Mcfly Stars Climbing Mountain For Charity

The British musicians are in training for the trek this summer (11) and are planning to donate all the funds raised to help educate underprivileged kids in boarding schools on the Peruvian island of Amantani.

And the bandmates have made the challenge extra tough, by agreeing to carry the equivalent weight of a child in their backpacks on the climb.

In a post on his Twitter.com page, Judd writes, "Any kind of donation to our justgiving page will go a long way. Leave a message when you donate so Tom and I can read them!"

Fletcher admits his training is in full swing, and he climbed Mount Snowdon in Wales on Thursday (14Jul11) for a practice run.

He tells his Twitter fans, "Tweeting from the summit of Mount Snowdon. Not bad for a morning's work."
