40,000 runners will take part in this year’s London Marathon, which takes in some of the capital’s most famous landmarks, including the Tower of London and Big Ben, before finishing on the Mall in front of Buckingham Palace. A large number of those taking part will be running for charity, whilst quite a few will tackle the 26.2-mile course in spectacular fancy dress. Over the years we’ve seen superheroes, animals and London buses take part!  The London Marathon also attracts some of the best distance runners in the world, so why not join the millions of people who line the iconic route for a fabulous day out.
