About the Event

Experience the Chilterns in their dramatic autumn guise at the Chiltern Ridge Winter 50K on Saturday, October 31, 2026, a classic ultra that masterfully blends the historic Ridgeway National Trail with the intricate woodland paths of the Chiltern Way. This scenic single-loop 50km journey starts and finishes in Berkhamsted, guiding you through the stunning Ashridge Estate and along high ridgelines offering expansive views, before diving into enchanting, frost-kissed woodlands on the return leg. As a UTMB World Series Index Race, it attracts a dedicated field while maintaining a welcoming atmosphere, with fully marked routes, four well-stocked aid stations featuring Precision Fuel & Hydration, and a generous 9-hour cutoff that encourages both seasoned ultra runners and ambitious first-timers. Organized with meticulous care by Runaway Racing, the event prioritizes runner safety and experience with mandatory kit checks, live tracking, and a supportive crew that epitomizes the best of the UK trail community. The crisp late-October conditions add a thrilling edge, transforming the trails into a vibrant tapestry of autumn colours and making every climb and descent a memorable challenge. Secure your discounted entry among the first 25 for a Halloween weekend adventure where the real treat is conquering one of Southern England's most beautiful and well-crafted ultra routes.
