The ballot for the 2027 TCS London Marathon will open on Friday, 24 April 2026.

The 2027 TCS London Marathon will take place on Sunday 25 April 2027.

The ballot for the 2027 TCS London Marathon will be open from 09:00 (BST) on Friday 24 April until 16:00 on Friday 1 May. It is a completely random draw, just like the National Lottery. The ballot results will be announced by early July.

Exploring a One‑Off Two‑Day Marathon for 2027

Last month it was stated that London Marathon Events is exploring the possibility of the 2027 TCS London Marathon taking place across two days.

Should permission be granted for this one‑off two‑day format it would take place on Saturday 24 and Sunday 25 April. All ballot entrants would automatically be entered into the ballot for both the Saturday and Sunday events (though they would only be able to take part in one), significantly increasing their chances of securing a place in the 2027 TCS London Marathon.

Hugh Brasher, CEO of London Marathon Events, said: “The TCS London Marathon is one of the most iconic and inclusive sporting events in the world and anyone can be part of it. Everyday heroes can stand shoulder to shoulder on the same Start Line as the fastest marathon runners on the planet, cheered on by hundreds of thousands of spectators lining the streets of London. It is a day like no other when humanity comes together with community, unity and purpose. Entering the 2027 TCS London Marathon ballot could be the first step towards becoming part of something truly life changing.”
