The Run South London Half Marathon takes place in Morden, Wimbledon and Merton on Sunday 14 March 2027 as a brand new closed road 13.1 mile race set to bring a fresh addition to the capital’s running calendar.

The route will take runners through a mix of leafy green spaces and well known local landmarks, offering a varied and scenic course across South London. With fully closed roads throughout, it provides a smooth and uninterrupted run that suits both first timers and those chasing a fast time.

As a new event, Run South London is already building momentum following the buzz of the TCS London Marathon, with many runners looking to channel that inspiration into their next goal. Early signs suggest it could quickly establish itself as a popular race in the region.

Entries are now open with Super Earlybird places currently available, offering a reduced entry price for a limited time. Demand is strong and these discounted spots are expected to fill quickly as interest continues to grow.

With strong community support expected along the route and a welcoming atmosphere planned, the 2027 edition looks well placed to become a key fixture for runners across South London and beyond.
