The target range shooting distance is 50 metres (160 ft). There are five circular targets to be hit in each shooting round. When shooting in the prone position, the target diameter is 45 millimetres (1.8 in); when shooting in the standing position, the target diameter is 115 millimetres (4.5 in). On all modern biathlon ranges, the targets are self-indicating, in that they flip from black to white when hit, giving the biathlete, as well as the spectators, instant visual feedback for each shot fired.
