Thames Meander Autumn 2026

Thames Meander Autumn offers a flat riverside race from Richmond, with 10K, half marathon, and marathon distances available on the Thames Path. All distances begin at the Petersham & Ham Sea Cadets HQ, near the river, and follow out-and-back routes. The autumn timing secures its place in the race calendar, with the appeal being simple: fast running on a well-marked towpath alongside the Thames. The 10K turnaround is at Kew Gardens Car Park. The half marathon extends to a point opposite Barnes Sports Club, and the marathon covers the half marathon route twice. The course is ideal for runners seeking a fast time because of its flatness, smooth surface, and clear navigation, supported by marshals. Aid stations are provided, and medical support is available throughout the event, making the setup suitable for both novice distance runners and those aiming for peak performance.
