The Lowdown
The TCS London Marathon, first run in 1981, has grown into one of the world's most celebrated road races and a cornerstone of the Abbott World Marathon Majors. Held each spring, the event combines elite competition with mass participation and a huge charitable ethos—raising hundreds of millions of pounds for good causes over its history. The 2027 race on 24 April continues that legacy with an innovative two-day format dubbed 'The TCS London Marathon Double: Two Days. One Event. 100,000 People.' The course is famously fast and largely flat, starting on Blackheath/Greenwich and weaving through riverside and historic London. Runners pass the Cutty Sark and Canary Wharf early on, cross the iconic Tower Bridge, and run along the Strand and past St Paul's Cathedral before the final stretch along the Embankment and a dramatic finish on The Mall in front of Buckingham Palace.
