We were called by York Ambulance Control to go to the aid of a fallen mountain biker somewhere near the glider station. The team were on a training exercise close by and were quick to respond. An exact location was not given but we established contact with the party on the hill and they gave us a description of the location so we could work out where they were. The casualty was dealt with and handed over to the ambulance crew. There were 23 members at this call, which lasted about 50 mins.
