London Marathon 2027

The TCS London Marathon is one of the seven Abbott World Marathon Majors and the largest marathon in the world by finishers: 59,830 runners crossed the line in 2026, a Guinness World Record. The course runs from Blackheath through Greenwich and Canary Wharf to a finish on The Mall, and the mass field is drawn by ballot roughly nine months before race day, alongside Good For Age places and more than a thousand official charity teams.

The London Marathon is one of the Abbott World Marathon Majors, running from Blackheath to The Mall past many of the city's landmarks. It combines an elite field with one of the world's largest mass-participation runs, and is a major fundraising event for UK charities.

Entry is by ballot, opened by London Marathon Events in the spring roughly a year ahead and drawn in July, with separate routes through Good For Age standards and official charity places.
