Chiltern Ridge Winter 50K
The Chiltern Ridge Winter 50K is a single-loop trail race held on 31 October 2026. The race starts and finishes at Berkhamsted Cricket Club and covers 50K with approximately 800 m of climb. The field is limited to 350 runners and the overall time limit is nine hours.
The route runs through Berkhamsted Common to Ashridge Estate, then joins The Ridgeway National Trail to Aldbury (CP1). From Aldbury the Ridgeway continues for about 13 km to Wendover (CP2). Runners then follow the Chiltern Way on more single-track and woodland paths back through Ashridge, finishing with a downhill approach into Berkhamsted.
The course is fully marked with orange arrow markers and ribbons, and marshals assist at road crossings and busier sections. A GPX file and printed maps are provided for navigation.

Full checkpoints offer water, coke, Precision Fuel & Hydration products, gels and chews, snacks, flapjacks and fresh fruit.

There is no parking at the venue; public car parks and a nearby train station provide access.
