So if you’re not already clued up, please be warned that this Saturday April 23, you’ll find 42,000 sweat-drenched runners stampeding through the city, trailing cheering fans, road closures, traffic restrictions in their wake. If your weekend plans involve a pleasant stroll through Blackheath, motoring over Tower Bridge, or picnicking in St James’ Park, please read on. Knowledge is power.

This handy map marks the overall route. But the roads on it aren’t necessarily closed all day. Instead, their closing times are staggered as the runners make their way from Greenwich to central London, meaning that an afternoon browsing the chichi shops of Blackheath is far from off the cards.

What bus changes will be happening?

Needless to say, there’ll be quite a bit of disruption for London buses too. Buses travelling on routes affected by the marathon will either be diverted, or will not run for that part of the journey. Visit for full info.

What about the Tube, London Underground and the DLR?

If you want to get somewhere fast on Saturday, these services are your best bet. The tube, DLR and overground will all be running extra services to cope with the increased demand. But do bear in mind that services with stops near the Marathon route are likely to be busy: especially the Jubilee, Circle and District lines, and the DLR.

Are there any National Rail travel restrictions due to the marathon?

Trains will be running as usual, although again, you can expect them to be extra busy if they’re heading to destinations on the marathon route.
