Half Marathon Events in London 2026-2027
Half-marathons are 13.1 miles (or 21.1km) long. These events are hugely popular, as the distance provides a good stepping stone challenge between 10km and the full marathon. In London there are a range of half-marathon events on offer. These races give you an opportunity to explore the landmarks, character, and scenery of the capital. The London Landmarks Half-Marathon takes you past all the most popular tourist attractions, while the Royal Parks Half goes through all the city's most beautiful parks. There are other running festivals available, which host the Hackney Half and the Richmond Half, where the atmosphere is certain to get runners excited. People running their first half-marathon might want to aim for under 2 hours, while those who are experienced runners can set themselves the prestigious challenge of running a half marathon in under an hour and a half (90 minutes). A half-marathon tends to burn anywhere between 1,000 and 2,000 calories, so it's a great workout.
