Shortly after 9 a.m. on Saturday, the man was riding on the Primeline freeride route, directly behind a colleague. According to initial findings, he crashed while riding down a drop. Two following bikers found him lying seriously injured on the trail. Together with another rider who had joined them and the mountain railroad rescue service, they immediately provided first aid. A Rega crew provided emergency medical care and flew the injured man to the Cantonal Hospital of Graubünden in Chur. He died there two days later from his serious injuries. The Graubünden cantonal police are investigating the exact circumstances of the accident in collaboration with the public prosecutor's office.
