“Biathletes must be able to strain to the physical limits, then immediately calm the body and slow the heartbeat to shoot a .22 caliber rifle, which they carry on their back as they ski, at small targets 50 meters away. When the biathlete is standing, targets are 115 millimeters, slightly larger than a CD. When the biathlete is prone (lying on the stomach) the target is 45 millimeters, about the size of a silver dollar.”
