The London running scene has never been more alive. Running crews, clubs and a ton of races: and half marathons are one of the most popular distance events.
The findarace.com calendar lists over 100 half marathon races in and around London every year. Check out our comprehensive 2026 - 2027 London half marathon race calendar below: you’ll find a race that’s perfect for you.
London's half marathon courses combine the capital's flat riverside paths with iconic park loops, making 13.1 miles feel surprisingly achievable. From Greenwich to Regent's Park, the even terrain lets you focus on pacing rather than battling hills, whilst landmarks along the Thames keep the route inspirational. First-timers find the distance manageable, and those chasing faster times can really open up on the flat sections. Looking for somewhere to train? Our Central London running routes and South London routes cover the best loops. Or, if you dancy stepping up to the full distance, why not try Marathons in London.
Winter and early spring see packed start lines as runners target sub-90 or simply tick off their first half, often using these as fitness checks before April's big goal. The network of segregated cycle paths and riverside trails means long stretches away from traffic lights and crossings.
Building up from shorter distances? Start with 10K runs in London or 5K races in London.
