Make a plan around the right edition

First choose whether you are planning for a participant or a spectator.

Match the correct day and leave meeting arrangements flexible until the relevant instructions are published. Start with the announcement below, then decide whether you need admission, a reservation or a place along a public route.

A date in a search result can belong to a completed edition. Check the year on the organiser’s page before sharing it with your group or paying for travel.

Next edition: Dates to be confirmed — this source check needs review.

Edition announcement source checked . All times Europe/London. Separately dated archive notes retain their own checks.

Source review needed. This planning check is older than seven London days or unavailable. Older event checks are excluded below; verify current details with the linked organisers.

What is actually confirmed?

The organiser explicitly announces a two-day Double TCS London Marathon for Saturday 24 and Sunday 25 April 2027. Do not use the old single-Sunday assumption. A website countdown is not an individual runner’s start assignment or a complete spectator timetable.

Entry routes and any paid extras have their own conditions. This guide does not claim an available race place or quote an unverified entry fee.

Keep your next step practical

Save the official page and the instructions that apply to your booking.

A festival window does not mean every activity happens every day, and a tournament date does not identify a particular match. If the timetable is not published, leave the exact start out of your plan rather than filling the gap with last year’s time.

Build a day that still works

Pick one nearby place for a break and agree how your group will get home.

For access needs, check the event entrance and the transport journey separately; a familiar station does not guarantee a step-free route to the viewing area. The transport guide explains the options, but the operator’s current notices and the organiser’s arrival instructions control the actual journey.

Questions, answered

Is the next edition confirmed?

24–25 April 2027. The organiser explicitly announces a two-day Double TCS London Marathon for Saturday 24 and Sunday 25 April 2027. Do not use the old single-Sunday assumption. A website countdown is not an individual runner’s start assignment or a complete spectator timetable.

Does this page guarantee a ticket?

No. An official edition announcement is different from an available ticket, reserved slot or invitation. Use the organiser’s current booking instructions.

Can I use an old programme to plan the visit?

Use it for background only. Routes, buildings, sessions, access and admission can change between editions; wait for the current instructions before relying on those details.
