TCS London Marathon

The TCS London Marathon is a mass-participation marathon held in London and is presented as one of the Abbott World Marathon Majors. The event is described by the organiser as the world’s biggest annual one-day fundraising event and is a major fixture on the international road‑running calendar. The race attracts elite athletes alongside a large field of mass participants and charity runners, creating a high-profile sporting and fundraising occasion that is notable for its partnerships and public support.

The course is the iconic London route that passes many of the city's landmark sights and is promoted as a spectacular urban marathon experience. Entry routes shown on the official page include ballot, charity places, Good For Age, Championship and international entries together with elite and wheelchair categories, and the event page explicitly shows charity places available for 2026. The race is organised by London Marathon Events Limited and the official event homepage holds links to results, entry information and charity team pages for further participant support.
