Bletchley Park to Paris

A 100 mile challenge to deliver an encrypted message before it's too late...

You are an elite member of F Section Special Operations Executive (SOE) and are about to be dispatched on a highly unusual mission behind enemy lines in France.  You will board a Halifax bomber departing from RAF Tempsford in Bedfordshire and parachute into France along with several containers of supplies for the French Maquis - the local resistance to the Nazi occupation.  From there you will need to crisscross occupied France, meeting with the French men and women whose acts of resistance represent astonishing bravery in the face of imminent danger. Each will supply you with a new code to crack with the answers adding up to a final message which must be delivered before time runs out.

It is up to you how you would like to complete the walk. The challenge can be completed over a few days, or the whole month, but you need to complete the 100 miles before the 31st July 2020. You can crack the codes as you go or save them up until the walk is complete. Once all the codes have been successfully decrypted you must decipher the final message to the secret agent in the heart of Paris.
