Last year's inaugural Shrove Tuesday pancake race at Greenwich Market was such a success that it's back again for 2014, looking to raise even more for Macmillian Cancer Support. Starting at 1pm, teams of four will flip their way through a series of heats to reach the grand final. Pancakes will be supplied but you'll need to take your own frying pan. There are prizes for the winning team and the best fancy dress. Kids races start at 4pm. Adult teams must register in advance by emailing firstname.lastname@example.org. Kids can just turn up and will be set off four at a time.
