The World Stinging Nettle Challenge is held in mid-June each year at The Bottle Inn in Marshwood, Dorset UK. What are nettles, and why would you eat something with the word 'stinging' in it anyway? Maybe we don't want to know.
The contest began in the late 1980s when two farmers argued over who had the longest stinging nettles in their field. Not sure how this led to a stinging nettle eating competition, but that is how the score is settled today.
In summary, competitors have an hour to eat as many neetle stalks as possible. Competitors eat the leaves off the nettle stalks, with the remaining bare stalks measured after an hour to find the winner.
