Land's End - John O'Groats

The big one in the UK! This route brushes the edge of Wales, and isn't the shortest route possible. It also pops up to Dunnet Head before finishing at the more southerly John O'Groats. This is a work in progress, so the roads aren't yet guaranteed to be cycle-friendly. It is designed for audaxers, spread over 5 days with around 300km of riding each day.
