What better way to spend your down-time than running around London, aggressively competing with strangers to see who can solve riddles and crack puzzles the fastest? This time round, the Citydash team have concocted a fiendish Valentine's event. Postmen have delivered so many Valentine's cards they have finally cracked. Cards, wedding invites and gifts are hidden all over Greenwich - can you save the wedding from being ruined? Join this crazy Citydash special to find out. After you've finished return to the pub for a catch-up with the rest of the teams, find out the results of the game and have a well-earned drink. Under 16s must be accompanied by a responsible adult. Game lasts 1 hour and 30 minutes.
