Chiltern Wonderland 50

About the Event

The CW50, a 50-mile single-loop race through the picturesque Chiltern countryside, offers runners an immersive journey through one of Britain's most historically rich landscapes. Spanning over 8 hours for many participants, this challenging course winds its way past charming villages steeped in history and cinematic landmarks that have graced British film and television screens.
Runners will encounter a total elevation gain of 5600 feet, weaving through varied terrain including rolling hills and lush woodlands. The route is meticulously marked to ensure navigational ease, while five well-stocked aid stations provide essential support throughout the race. Full medical coverage adds an extra layer of safety for all participants.
Organized under a full UK Athletics permit granted by the TRA (Trail Running Association), this event guarantees high standards and professional management. For added peace of mind, runners have the option to purchase XCover insurance, which offers financial protection in case unforeseen circumstances prevent them from participating.
The CW50 promises not just a physical challenge but also an unforgettable experience that blends natural beauty with cultural heritage.
