Bewl Water Autumn - Overview

Bewl Water Autumn is a bi-annual race series that starts near the Bewl Water Visitor Centre in Lamberhurst, Kent. The routes follow the reservoir and use a combination of undulating rural wooded trail and some quiet country lanes, with regular views of the lake. Event dates listed include 13 June 2026 and 12 September 2026. Course maps, GPX routes and a route video are available for each distance. The organiser notes that distances were measured with a Garmin Fenix 6X Pro-Solar watch and that the marathon course is slightly longer than the standard marathon distance.
