Organised in collaboration between Northern Ride & Birdsall Estates, The Yorkshire Mountain Bike Marathon is a traditional challenge mountain bike event that takes place around the private, normally un-accessible 12,000-acre Birdsall Estate. The event is inclusive and suitable for a variety of abilities, some will look to get a fast time and others will look to complete the challenge in their own time. However everyone will get to experience the natural singletrack, woodland and unique terrain.
