Land’s End to John o’ Groats is the traversal of the whole length of the island of Great Britain between two extremities, in the southwest and northeast. The traditional distance by road is 874 miles (1,407 km) and takes most cyclists 10 to 14 days; the record for running the route is nine days. Off-road walkers typically walk about 1,200 miles (1,900 km) and take two or three months for the expedition. Two much-photographed signposts indicate the traditional distance at each end.

The challenge is a formidable one especially if the challenge is to be completed within a given time. Many competitors complete the challenge to fulfil a lifetime ambition often accompanied by a commitment to raise funds for a charity close to their hearts.
