Are you up to the challenge? 

30 miles in 30 days. Choose your quest. Solve the puzzles, stretch your legs. And help fund the Parkinson’s UK Brain Bank. For every 2 miles you walk, you'll receive a cryptic puzzle to solve. Every puzzle you solve will unlock more of your quest and take you a step closer to completing the Brainbox Challenge. 

Complete the quest to retrieve the legendary dragon scale and tackle easier level puzzles with Arthur's Quest. Or test your brainbox skills and take on our harder puzzle option and travel through key Parkinson's UK milestones by taking part in Arthur's Milestones.  

Which challenge will you conquer?

Arthur's miles

Your time machine malfunctioned and it's taken you back to 1969. Solve the puzzles to power the time machine and get you back to present day. There'll be challenges along the way, as you explore Parkinson's UK milestones through the decades.
