The Route

Take on a brilliant 13.1-mile route through the borough’s open green spaces and pass through Merton’s bustling streets including Morden and Wimbledon. Starting and finishing in Morden Park, the route takes runners through the heart of South London, passing the world-famous All England Lawn Tennis Club, the stunning surroundings of Wimbledon Park and Wimbledon Common, the historic Wimbledon Windmill, and the characterful streets of Wimbledon Village.

The course then continues through Raynes Park, one of the capital's key suburban communities, where runners will experience its lively atmosphere before passionate local support guides them back to Morden Park for a memorable finish.
