Richmond Half Marathon Autumn 2026

The Richmond Half Marathon Autumn is a London half marathon starting at 9:00 AM. Its course follows Richmond, Kew, and the River Thames. This RUNFEST event begins inside the Royal Botanic Gardens, Kew, and concludes at Old Deer Park in Richmond. The finish area features a fitness expo and live music. Public entries may sell out, with charity places often filling the remaining field. The route enters Kew Gardens before passing Ham House, Richmond Palace, Teddington Lock, and sections of the Thames. The course is clearly marked, measured, and England Athletics certified, with chip timing and results available immediately. The weekend also hosts the Richmond RUNFEST Marathon and Richmond 10k, meaning half marathon runners share the event with other runners, local charities, and supporters who receive free entry to Kew Gardens. Finishers get a medal, a tech tee, and post-race refreshments including water, juice, fruit, and a chocolate bar.
