The traditional TCS London Marathon route takes in some of the most famous landmarks in the city and spectators are welcome to watch from almost anywhere along the 26.2-mile stretch. Please note that some parts of the route – including the areas by Cutty Sark and St James’s Park – do get very busy on Marathon Day, while The Highway will enable you to see everyone pass twice!
