Other information about the TCS London Marathon 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 24th April and Sunday 25th April 2027. All ballot entrants would automatically be entered 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.

So, for now, keep both dates free!

Currently, Sunday 25th April 2027 is the confirmed date for the event if a one day event takes place.
