London Landmarks Half Marathon


We are writing to advise you that, subject to Public Health and Government guidelines, on Sunday 1 August 2021, the third edition of the London Landmarks Half Marathon ( will take place in Central London for 14,500 participants and will involve some road closures in your area. We are closely monitoring advice regarding the pandemic, and are working closely with the local authorities to put a number of measures in place to ensure that the event is delivered to the required safety standards for the participants, spectators, event crew and local residents on event day. We can assure you that the event will only go ahead if Public Health and Government guidelines allow.  

The event is organised by baby charity, Tommy’s ( to raise crucial funds, along with fundraising for many other good causes.  Over £17m has been raised to date through the first three years of the event. While participants run past some of London’s most iconic landmarks, the race’s new 2021 theme will shine a light on how we are coming together as a nation during the Covid-19 pandemic. 

Please see attached a map and table which shows the road closures and key timings. The route has some subtle changes from previous years to accommodate the safety measures. Within Westminster the most notable change is the start area layout. Specifically, the start line will be located at the east end of Duncannon St just before the junction with the Strand. Staying in Westminster the route layout has changed around Aldwych and for this event the route will take participants along Melbourne Place. Within the City of London the route has been extended to cater for the move in the start line. This extension will see participants using Noble St, Oat Lane and Staining Lane which are new for 2021. As per previous events, the route will be covering 13.1 milesthrough both the City of London and City of Westminster to then finish on Whitehall. Road closures will be in place along the route between 05.00 to 19.00, however closure and reopening timings will vary within this timeframe across the route – please refer to the attached document for specific timings in your area. If there is anyone else in your building you think this may affect, please do share this information with them. 

We are currently working closely with the local authorities and TFL on the traffic management required to manage the event and will be in touch shortly with further details on these road restrictions and their timings. In the meantime, if you have any concerns please do not hesitate to get in touch.
