A bike rider suffered multiple injuries and was airlifted to hospital after he crashed into a tree on a fast downhill route at a mountain bike centre in Todmorden.
The Calder Valley Search and Rescue team was called on Sunday to assist the Yorkshire Ambulance Service with the treatment and evacuation of an injured mountain biker.
Once stable the patient was stretchered the short distance to the waiting ambulance.
Due to his injuries the decision was made to fly the casualty to hospital via the Yorkshire Air Ambulance.
Team members identified a landing site for the helicopter and once landed transferred the casualty from the ambulance to the aircraft for his flight to hospital.
