Have an extra jolly holiday season by dressing up as the man of the moment and running around London at this 'non-profit, non-political, non-religious and non-sensical' celebration of Christmas cheer. This flashmob-style gathering will see three huge groups of Santas wandering through the city giving out gifts and free hugs, singing carols and occassionally popping to the pub. Towards the end of the routes the groups join together into a huge throng of merry fellas (plus a few elves and reindeer – they're allowed to join in, too). Starting points are announced on the Santacon website in the lead-up to the event, and Santa herders will lead the way on the day. Just remember to go full suit, because those who just throw a hat on will be ostracized in a most un-Christmassy manner.
