If you were on Bankside on Friday morning and thought you saw three giant pints of beer, don't worry - you weren't hallucinating.
The southern end of the Millennium Bridge
was the start point for the annual Giant Pint Run to promote Cask Beer Week. Fuller's, Young's, Shepherd Neame and McMullen breweries are working together to encourage consumers to turn their attention to real ale
Three giant pints, representing Young's, McMullen and Fuller's wobbled their way across the Millennium Bridge
, into Smithfield Market and across the City, ending in Leadenhall Market.
The annual event, which sees the giant pints handing out vouchers for free beer, raises awareness of cask beer.
These activities were only the beginning of a week-long event, which runs from September 16-25. Cask Beer Week is supported by the Independent Family Brewers of Britain (IFBB), and aims to make the whole country aware of the fine and enjoyable qualities of cask beer.
