Around 16,000 people run the Royal Parks Half Marathon. Several hundred thousand more are affected by it without ever having heard of it, because the course closes a significant part of central and west London for most of a Sunday morning.
If you are running, the organisers will tell you everything you need. This page is mostly for the other group: anyone trying to cross London, reach an airport, or simply get somewhere on Sunday 11 October 2026.

The closures matter more than the race
A half marathon through four royal parks sounds contained. It is not, because the course does not stay inside the parks — it uses the roads that connect them, and those roads are the spine of central London.
Park Lane and Hyde Park Corner together carry most north–south traffic on the west side of the centre. Constitution Hill and The Mall connect Westminster to Green Park. When those go, there is no elegant alternative: traffic displaces onto Edgware Road, Marylebone Road and Victoria, all of which then run heavier than a normal Sunday.
Closures generally begin early — before the 9am start, and in some sections from the previous evening for setup — and roads reopen in stages through the early afternoon rather than all at once. A route that was blocked at 10am may be clear by noon, or may not.
Which journeys to rethink
Airport runs are the ones that hurt. A journey from central or north London towards Heathrow would ordinarily run west through Hyde Park Corner and Knightsbridge, or along Park Lane to reach the A4. On race morning that approach is compromised for several hours.
The workaround is to go north of the park — Marylebone Road to the Westway and out to the A40, or the North Circular if you are starting further out — rather than attempting the direct westward line. It is longer in distance and shorter in time. Our Heathrow to London route guide covers the usual timings; on 11 October, add 45 minutes to anything crossing the centre and treat that as a floor.
Journeys to Gatwick south of the river are barely affected. Stansted and Luton runs from north and east London are fine.
Hotel checkouts around Mayfair, Knightsbridge and Belgravia are the other pinch point. These are exactly the streets inside or beside the closure ring, and a Sunday-morning checkout with luggage is a poor time to discover the road outside is shut. If you are staying in that area, ask for the pickup to be arranged from a street outside the cordon and walk the bags round.
The second event on the same day
Later that afternoon, the NFL plays at Tottenham Hotspur Stadium, kicking off at 2:30pm with a crowd of around 62,000.
The two events do not overlap geographically. What they do is bracket the day: road closures across the west and centre in the morning, and a stadium cordon in the north from lunchtime onwards. Anyone travelling between the two halves of the city on 11 October meets one or the other, and possibly both.
If your journey involves crossing London that day, the middle of the day — roughly 12pm to 1:30pm — is the clearest window. Our NFL London games guide covers the stadium side of it.
Watching the race without getting stuck
For spectators, the useful thing to know is that the course loops, so a well-chosen spot gives you two views of the same runner.
The park sections are the pleasant ones and the least congested for getting away afterwards — the stretches inside Kensington Gardens and the western side of Hyde Park are far quieter than the finish area. The Buckingham Palace and Mall sections are the photogenic ones and correspondingly packed.
Getting away is the part people underestimate. The finish area empties 16,000 tired runners plus their families onto a handful of park exits, and vehicle access near Hyde Park is restricted while the closures hold. Arrange a pickup well away from the park — Paddington, Victoria or Marble Arch — rather than at the nearest gate.
Frequently asked questions
Q: When is the Royal Parks Half Marathon 2026? A: Sunday 11 October 2026. The first wave starts at 9am in Hyde Park and the final wave sets off around 9:45am, with runners on the course through the late morning.
Q: Which roads close for the Royal Parks Half Marathon? A: Typically Park Lane, Hyde Park Corner, Constitution Hill, The Mall, Birdcage Walk and the carriage drives inside the parks, with some sections closing the previous evening for setup. Roads reopen in stages through the early afternoon. The organisers publish the definitive list shortly before race day.
Q: Does the Royal Parks Half Marathon affect getting to Heathrow? A: Yes. The usual westward routes through Hyde Park Corner, Knightsbridge and Park Lane towards the A4 are compromised for several hours. Go north of the park via Marylebone Road and the Westway to the A40 instead, and allow at least 45 minutes more than usual.
Q: What time do the roads reopen after the race? A: In stages through the early afternoon rather than all at once, with the finish area around Hyde Park the last to clear. Between roughly 12pm and 1:30pm most of central London is moving again.
Q: Is anything else happening in London on 11 October 2026? A: Yes — an NFL game kicks off at Tottenham Hotspur Stadium at 2:30pm with around 62,000 spectators. The morning closes the west and centre; the afternoon congests the north.
Q: Where should spectators arrange a pickup? A: Away from the park. Vehicle access near Hyde Park is restricted while closures hold and the finish area is crowded, so Paddington, Victoria or Marble Arch work far better than the nearest park gate.
The bottom line
If you are crossing London on 11 October, go north of Hyde Park rather than through it, add 45 minutes to any airport run, and aim for the midday window between the race clearing and the stadium filling.
