A brand-new half marathon called “Run South London” has been officially announced, with the first race scheduled for 14 March 2027 in London.
The event is being organised by The Great Run Company in partnership with Merton Council. It aims to bring a major new running event to south London, welcoming participants of all abilities.
A New Addition to London’s Running Calendar
Run South London will be a 13.1-mile (half marathon) race, designed to showcase some of the most attractive and well-known areas in south London.
The route is expected to include:
- Tree-lined parks and green spaces
- Historic streets around Wimbledon
- Views of well-known sporting venues
The race will start and finish at Morden Park, a large open space in south London with strong transport links, including access to the London Underground Northern line.
A Fully Closed-Road Race Experience
Organisers have confirmed that this will be south London’s only closed-road half marathon, meaning roads along the route will be temporarily closed to traffic.
Closed-road events are popular among runners because they:
- Provide a safer running environment
- Allow better race performance
- Create a more enjoyable experience for participants and spectators
Open to Runners of All Levels
The event is designed to be inclusive and accessible. It will welcome:
- First-time runners
- Amateur fitness enthusiasts
- Experienced athletes
This approach aims to encourage more people to take part in physical activity while also building a strong community atmosphere.
Boost for Local Economy and Community
Organisers expect the event to attract thousands of runners and spectators, bringing benefits to local businesses and services.
According to an independent estimate, the race could generate up to £1.7 million annually for the local economy.
This includes increased demand for:
- Hotels and accommodation
- Restaurants and cafés
- Retail shops
- Local transport services
Community groups, schools, and sports clubs are also expected to take part, helping to create a wider positive impact.
Supporting Charities and Fundraising
Like many major running events, Run South London will provide opportunities for participants to raise money for charities.
Fundraising runs are an important part of the UK running culture, supporting causes such as:
- Health and medical research
- Community services
- Social support programmes

Why This Event Matters
London already hosts several major races, but south London has had fewer large-scale running events compared to other areas.
Run South London aims to:
- Fill that gap in the city’s running calendar
- Promote health and fitness
- Highlight south London’s parks and communities
With strong organisation and local support, it has the potential to become a regular annual event.
Final Thoughts
The launch of Run South London marks an exciting development for runners and residents alike. By combining a scenic route, community involvement, and economic benefits, the event is set to become a key highlight in London’s sporting calendar from 2027.
