Planes, trains and automobiles, or perhaps a human drawn cart.

These are just some of the options Tim Moss can choose from as he attempts to circumnavigate the globe in 80 different ways.

The West Molesey student is to attempt the extraordinary trip during a six-week break this summer to raise money for TreeHouse, a charity for children with autism.

He and two others hope to use transport ranging from London buses to parachutes, helicopter and even an underwater jetpack.

They will make the trip using each mode of transport only once, when the team leaves in mid-June.

Team leader Tim, a student at University College London (UCL), which is funding most of the expedition, said: "I came up with the idea at the end of a UCL expedition I was on last year. I sat down with two friends and thought, Now what can we do next year?' "I knew it had to be big, and travelling around the world came up straight away.

"Eighty days had been done, but 80 ways we thought was worth a try.

"I work with a child with autism as a home tutor and I have seen first hand how crucial the right kind of education is for his chances to live independently in the future.

"When I heard about the pioneering work TreeHouse was doing, I knew I had to help them.

"They really are making a difference for children with autism."

TreeHouse, founded in 1997, educates 40 children with autism in its specialist school in north London. It also provides support for parents and professionals around the country.

Author Nick Hornby was part of the group that set up the charity.
