Marathons In & Near London 2026 - 2027

The most comprehensive list of Marathons in and near London in 2026 - 2027. Find your perfect race!

London hosts marathons that make the most of the capital's flat terrain and iconic riverside routes. From the Thames Path to Regent's Park, courses here favour steady pacing and fast times across historic streets and open green spaces. For a full breakdown of where to run in the capital, see our guide to running in London. Runners chasing PBs find the even ground ideal, whilst those after something shorter with the same urban backdrop can try Half Marathons in London.

Year-round events mean you can race through crisp autumn mornings in Richmond Park or spring sunshine along the embankment. Many runners use these as serious training runs for the big one in April, testing their pacing on similar flat urban terrain. The city's network of riverside paths and Royal Parks keeps you off roads for surprisingly long stretches. Looking to build up gradually? Explore 10K runs in London or 5K races in London.
