The TCS London Marathon 2026 will take place on Sunday 26 April 2026, bringing together thousands of participants to complete the iconic 26.2-mile marathon in London.

Alongside the main event, the TCS London Marathon My Way allows participants to take on the same marathon distance in their own location. This flexible format enables individuals to complete the miles in a way that suits them, whether by running, walking, or completing the distance in stages.

Participants taking part in either the London Marathon or the London Marathon My Way will be fundraising in support of The Leanne Fund, helping to raise vital funds to support children, young people, and families living with Cystic Fibrosis across Scotland.
