The following is an extract from the (now defunct) endtoenders.co.uk  website :

Travelling from Land's End to John O'Groats (or the other way) - an 'end to end' - is not a totally modern idea, we have records dating back to the 1800's. Over the years, the trip has been done by many tens of thousands of people and in a number of amazing ways, however, it is a unique challenge and quite an incredible achievement.

Many will remember hearing of Dr Barbara Moore and the Billy Butlin walks of the 1960's, Ian Botham did it twice and in March 2005, BBC Radio 1 DJ Chris Moyles in support of Comic Relief and James May from BBC's Top Gear in support of the RNLI.

By doing this journey you will join the ranks of the famous and be able to claim your 15 minutes of fame!

Methods of Transport

The most popular forms of transport are walking, driving or cycling but it has also been done by a Harrier Jump Jet, turbo charged JCB digger, wheelchairs, 'celebrity cars' and a motorised bath tub. Someone even posted himself and literally became 1st class mail!
