Thousands of runners are set to hit London’s streets on Sunday as the Oysho Royal Parks Half Marathon arrives in the capital.

The event was first launched in 2008, and bills itself as the first and only half marathon through the centre of London.

It was set up by The Royal Parks charity as an annual fundraising initiative to help conserve and enhance London’s Royal Parks, while enabling charities of all sizes to be involved in a major challenge event.

The event has raised over £80 million for more than 1,900 UK charities.

This year’s event comes as a record 1.33million people entered the London Marathon 2027 ballot, showing a growing popularity for mass-participation running events in the capital.

The 13.1-mile Oysho Royal Parks Half Marathon route takes in many of the capital’s world-famous landmarks.

It also passes through four of the capital’s eight Royal Parks - Hyde Park, Green Park, St James’s Park and Kensington Gardens.

Starting in Hyde Park and finishing in Kensington Gardens, more than 18,000 runners will pass Horse Guards Parade with views of the London Eye, run along The Mall twice, and pass both Kensington Palace and Buckingham Palace.

Although there are some gentle undulations, it is a generally flat course, making it a good option for both beginners and experienced runners attempting to set personal best times.

Participants will cross the finish line in front of two iconic London landmarks - The Albert Memorial and the Royal Albert Hall.

The event village in Hyde Park is a short walk from the finish line.

The Oysho Royal Parks Half Marathon officially kicks off at 8.45am.

The Event village and Baggage Tent will be open from 7.30am, with wave loading opening from 8.05am.

Participants have until 2pm to complete the race, with the Event Village closing by 4pm.

Due to local road closures, public transport is your best bet to reach the event - whether you’re a spectator or a participant.

Many Tube stations are within walking distance from the start and finish lines, including Hyde Park Corner, Green Park, Knightsbridge, South Kensington, Victoria, Marble Arch, and Lancaster Gate.

Directions from each nearby station can be seen on the Oysho Royal Parks Half Marathon YouTube page here.

Runners and spectators have been advised that there are planned engineering works on Race Day on the Circle line from Edgware Road to Aldgate via Victoria and on the District line from Tower Hill and Edgware Road to Ealing Broadway, Kensington (Olympia), Richmond and Wimbledon.

There are plenty of great places to watch along the route, with sponsors and charities at spots along the route to cheer runners on and keep them moving.

The Mall is located between Mile 1 and 2 and between Mile 4 and 5 on the route, allowing spectators to spot runners in two directions.

Serpentine Road in Hyde Park also sees runners in both directions - between Mile 5 and 6 and between Mile 8 and 9.

It is a popular spot, with charities creating a lot of atmosphere.

The Albert Memorial is the perfect spot near the finish line to cheer runners home.

Many central London roads will be closed for the event.

Roads within Hyde Park will be closed from 12.01am on Sunday October 11 until 5am on Monday October 12.

Roads within St James’s Park will be closed from 6am until 6.30pm on Sunday, and roads within Westminster will be closed from 7am until 12.30pm.
