Take on Operation Bletchley. Your codebreaking challenge 

Taking place twice a year, in July and January, your mission is to cover the miles, crack the codes and uncover the secret message you need to deliver to Winston Churchill before time runs out. 

From 1st January, take on one or both of our winter missions:

  • Land in Berlin and cover 40 miles on foot through Soviet territory and decrypt vital intelligence to beat the blockade.
  • Embark on an undercover 80 mile journey across Yugoslavia arranging supply drops and organising attacks in our Balkans mission. 

Test your codebreaking skills as you conquer one of our epic challenges. Immerse yourself in the incredible stories of some of the bravest people who helped us triumph against our foes. Can you crack the final code before time runs out?

You can take part from anywhere in the world using your phone, fitness tracker or a good old map. 

Choose from one of three difficulty levels - junior, codebreaker or cypher expert. Be a part of something incredible this winter whilst supporting soldiers, veterans and their families. 

You have one month to cover the miles, crack the codes and deliver the final secret message.

REGISTER NOW - your mission starts on the 1st of January.
