Time Out says
Watch teams decked out in fancy dress grab their crepes and run through Brick Lane's cobbled side streets in pursuit of this coveted pancake race winner's engraved frying pan. Entrants to this very silly fundraiser for the London Air Ambulance must register in advance but you can still egg on your favourite from the sidelines. Email email@example.com to enter a team of four (or enter on the day if they bring a donation). All entrants will be rewarded with hot pancakes. Arrive at 12.15pm for a 12.30pm start.
