Chiltern Ridge Winter 50K
The Chiltern Ridge Winter 50K is a single loop trail race held on 31 October 2026 with a distance of 50K and around 800 m of elevation. The event starts and finishes at Berkhamsted Cricket Club and has a maximum field of 350 runners. There is an overall time limit of 9 hours and the minimum age for entry is 20 years; no qualifying standard is required.
The route follows local trails through Berkhamsted Common and National Trust Ashridge Estate, joins The Ridgeway National Trail to Aldbury and Wendover, then returns via the Chiltern Way through woodland back to Berkhamsted. Navigation is fully marked with orange arrows and ribbons and marshals are stationed at road crossings and busier sections. All runners must carry a digital GPX of the route on a watch or phone as backup.
On course there is a water point at 11.9 km and three full aid stations at Aldbury, Boswells Farm (Wendover) and Wigginton Village Hall. Aid stations provide water, cola, pre-mixed electrolyte drink, gels and chews, snacks such as crisps and biscuits, and fresh fruit. The race is licensed by the Trail Running Association and is an UTMB World Series index race. Required kit includes a mobile phone, refillable hydration (0.5 L minimum), route GPX, waterproof jacket, warm hat and gloves, an extra long sleeve layer, head torch, and payment method.
