The London Marathon 2025 is set to take place on Sunday, April 27 — and with more than 56,000 participants expected, road closures across the capital are inevitable.
To ensure runners can safely complete the 26.2-mile route, major roads will be closed throughout the day.
The race crosses five London boroughs — Greenwich, Southwark, the City of London, Tower Hamlets and Westminster — meaning the event will impact far more than just those lacing up their trainers.
Here’s a full breakdown of everything you need to know about road closures on the day.
