10k Runs in the South East 2026-2027

10k runs in the South East: 302 10K races in 2026 and 2027, from Brighton to Oxford, with dates, start locations and entry links. The South East has the deepest 10K calendar outside London, and plenty of variety within it. The seafront races at Brighton, Eastbourne and Portsmouth are flat and quick, the Thames valley around Reading, Oxford and Henley gives riverside courses, and the South Downs, the Chilterns and the Surrey Hills turn a 10K into a proper trail outing. Add the Kent coast, the New Forest and the Isle of Wight, and most runners here have a dozen races within an hour's drive in any given month.

10ks worth knowing in the South East

The Brighton Marathon Weekend in April has a 10K along the seafront on the same morning as the marathon, and the Southampton Marathon Festival in May starts a 10K from Guildhall Square alongside its half and full. The Oxford Town and Gown 10K in May runs through the city centre and the University Parks, and the Surrey and Sussex club scene fills the rest of the year with measured 10Ks on country lanes. Summer brings evening races on the coast and in the Thames-side parks; winter belongs to the trail 10Ks on the Downs. Check the race page for the 5K, half marathon or fun run that often shares the day, and use the distance slider if you are after a 10-miler.
