How road closures and transport changes will affect south east London on race day
From the early hours of race day, key arteries through south east London will be reshaped as miles of tarmac are handed over to tens of thousands of runners. Sections of Blackheath, Greenwich, Lewisham, Deptford and Bermondsey will see rolling closures, with parking suspensions, diversions and barriers in place well before the starting gun. Residents should expect bus routes to be shortened or redirected, taxi access to be restricted, and familiar rat-runs to be blocked off as stewards manage crowds and emergency access. For many, the only practical way to move around will be on foot or by Tube, rail or Overground, which are expected to run enhanced Sunday services to cope with spectators.
Transport planners are urging people to build in significant extra time if they must travel, especially across the route. In particular, river crossings, main junctions and roads feeding into the start areas will be under tight control, with limited opportunities to turn off once you’re in a closure zone. To help you navigate the disruption, here are the broad patterns drivers and public transport users can expect:
- Road users: Avoid non-essential car journeys; use signed diversion routes and check live mapping apps before setting off.
- Bus passengers: Many services will terminate short of their usual end points; some will not serve Greenwich and Deptford at all during peak race hours.
- Rail and Tube: Trains are likely to be busy from early morning, particularly into Blackheath, Greenwich and London Bridge.
- Local residents: Moving cars overnight may be necessary where parking bays are suspended; access permits won’t override hard closures.
| Area | Likely Impact | Best Option |
|---|---|---|
| Blackheath | Early full closures, limited vehicle access | Arrive/leave before dawn or use rail |
| Greenwich town center | Heavy crowds, road lockdown for hours | Walk or use DLR/rail, avoid driving |
| Deptford & Surrey Quays | Rolling closures, bus diversions | Overground and local trains |
| Rotherhithe & Bermondsey | Bridge and riverside route restrictions | Jubilee line, plan crossings in advance |
Best spectator spots and local vantage points to watch the marathon in comfort
Whether you want a selfie backdrop of Cutty Sark or space to spread out a camping chair, there are plenty of pockets along the route that offer both atmosphere and comfort. Greenwich and Blackheath give you big open spaces and easy access to cafés and pubs,while Canary Wharf‘s broad pavements and modern plazas mean decent views without being crushed at the barriers. For families,the quieter stretches through Rotherhithe and Limehouse often have more elbow room,shorter queues for toilets and nearby playgrounds,making them ideal if you’re planning to stay put for several hours.
Closer to the finish, St James’s Park and The Mall deliver the most dramatic moments, but they also fill up fast, so arriving early is essential if you want a front-row view. Many locals opt for elevated spots such as balcony bars, riverside terraces or upper-deck seating on cafés that overlook the course, swapping the crush for a coffee and a agreeable chair. Look out,too,for community hubs and churches along the way that open their doors on race day,offering refreshments,indoor seating and big-screen coverage so you can follow loved ones without standing for hours on the pavement.
- Best for families: Greenwich Park, Rotherhithe residential stretches
- Best for atmosphere: Cutty Sark, Tower Bridge, The Mall
- Best for comfort: Canary Wharf plazas, riverside pubs with terrace views
- Best for photos: St James’s Park, Embankment, near Westminster
| Area | Nearest station | Comfort factor |
|---|---|---|
| Blackheath | Blackheath | Open space, good picnic spots |
| Cutty Sark | Cutty Sark DLR | Cafés, pubs, classic views |
| Canary Wharf | Canary Wharf | Wide pavements, seating, toilets |
| St James’s Park | St James’s Park / Westminster | Benches, food kiosks, finish-line buzz |
Practical tips for runners and supporters from last minute training to what to bring
Even if you’ve left training later than planned, there’s still time to make smart tweaks rather than heroic mistakes.Focus on short, easy runs to keep your legs loose, add one or two race-pace efforts instead of new long runs, and prioritise sleep and hydration over cramming miles. Avoid anything radically different – from brand-new shoes to an untested energy gel – as familiarity is your best defence against mid-race surprises. The day before, think logistics: know your start zone, your route to the start line, and agree a clear meeting point for after the finish that isn’t right by the barriers, where phone signal can vanish.
- For runners: Pack your kit the night before – including safety pins,plasters and a throwaway layer for the chilly wait in the pens.
- For supporters: Wear luminous colours, bring a portable phone charger and write runners’ names on a big sign so they can spot you in the crowds.
- Fuel & comfort: Carry snacks, water and tissues; runners should pre-pack gels and salt tablets in a belt they’ve already trained with.
- Weather-ready: Think layers,ponchos and sunscreen – London’s April conditions can swing from drizzle to sun in a single hour.
| Runners’ bag | Supporters’ bag |
|---|---|
| Race kit & spare socks | Route map & tracking app |
| Vaseline & blister plasters | Snacks and bottled water |
| Gels you’ve tested in training | Marker pen & homemade sign |
| Foil blanket or light jumper | Power bank & compact umbrella |
