2 pm this Thursday (17 December) at Farringdon Station

I'm doing a two-hander with fellow guide Denise this Thursday - a quick walk (about 75 minutes) looking at Christmas through the ages, all of them illustrated in the amazing area of Clerkenwell. A nice gentle workout, for body and brain, to clear the fug of festive lunches and parties - what's not to like?

Not only that, but we are reflecting the relative shortness of the walk in the bargain price of £4 per head. Less than the price of a fizzy lager, and we promise not to give you a hangover...
