The legendary London Marathon is an event like no other. The race has been going since 1981 and is held every spring, taking runners from starts in Greenwich and Blackheath, winding around the East of London and following the route of the Thames through to the final high-drama finish in The Mall to enormous and super-enthusiastic crowds all the way.  

The route takes in Greenwich park, the Cutty Sark, Wapping, Tower Bridge, the Tower of London, the London Eye and the Houses of Parliament among the many iconic experiences for runners and their supporters alike.  

If you join Team Marsden we'll be with you every step of the way to help you through training and fundraising, providing a running vest, a friendly team WhatsApp group, fundraising guides and one-to-one support throughout your whole running journey.
