There are unlikely to be any world-class athletes entered, but in their own unique way, entrants into this weekend's Great British Beerathon deserve some admiration.
Taking place on Saturday 3 July, the annual race starts at the Hoop and Grapes pub in Farringdon in Central London. The five mile event combines running with eating and drinking traditional British pub fayre.
After each mile circuit around the nearby City, runners must overcome a 'slobstacle' in the pub beer garden, starting with a pint of bitter and a scotch egg after mile one. Following miles two and three they must tackle a pint of lager and pasty and a pint of cider and a pork pie.
Before heading out on the fifth and final mile they must consume a Guinness and a crumble. Last year saw 79 runners take part with Rob Foster smashing the world record to win in a remarkable 37mins 59secs. Registration is still open and costs £25 and is only open to those over 18.
