Since 2015, mountain bikers from across England and beyond have descended on an otherwise peaceful corner of County Durham to take part in the Hamsterley Beast.
Each year since then, the event has grown in size. The 2018 event raised a staggering £27,000 for the Great North Air Ambulance Sevice.
In just three years, riders in the Hamsterley Beast have helped raise nearly £60,000 for GNAAS. Keep an eye on this page for future info about The 2019 event.
