Bewl Water Spring 10km, Half Marathon, Marathon & Ultra 50km

Discover one of the UK’s top-rated trail race series at Bewl Water. Set in the heart of Kent, this bi-annual race series offers a variety of distances—10K, Half Marathon, Marathon, and 50K Ultra—all beginning near the Bewl Water Visitor Centre in Lamberhurst. The races take place on an undulating mix of rural wooded trails and quiet country lanes, with panoramic views of the reservoir for much of the route. Each course has been carefully measured using a Garmin Fenix 6X Pro-Solar, offering runners the most accurate trail distances possible. Whether you’re looking to challenge yourself with an ultra-distance, enjoy a scenic half, or dip your toe into trail running with a 10K, there’s something here for everyone. This event consistently earns accolades, including a Runner’s World “Top 10 Races in the UK” mention, thanks to its natural beauty, professional organisation, and supportive atmosphere.
