Can you cover the 50 mile route, on foot, throughout the month of July, cracking the codes as you go? With three levels to chose from, junior codebreaker, codebreaker or cypher expert, can you figure out the code and deliver the message before it’s too late?


Your mission…

It’s 1941 and the United Kingdom is in terrible danger. Luftwaffe bombs are raining down on towns and cities across the nation. The Royal Air Force guards the skies and the Navy protects the seas, but the threat of invasion has never been higher. German spies could destroy our telephone network at any moment, so the Home Guard is tightening up security around the capital.

We need you to help us secure a new line of communication from Bletchley Park to the Cabinet War Rooms in London. Walk or run the 50-mile route, making contact with key agents along the way and decrypt their coded messages.

Can you get inside the minds of the great historical code breakers, rack up the miles on foot, deliver the final message to Winston Churchill and complete your mission next summer.
