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 2017 Beast sold out twice, even after more places were released to satisfy the incredible demand. More than 480 riders took part last year alone.
All of the money raised through the event supports the Great North Air Ambulance Service (GNAAS). In just three years, riders in the Hamsterley Beast have helped raise nearly £60,000 for GNAAS.
