Biathlon gliders are athletes who compete in the winter sport of biathlon, which combines cross-country skiing and rifle shooting. The term 'biathlon glider' refers to the skis used by biathletes, which are designed to glide quickly over snow and ice. The skis used in biathlon are typically shorter and lighter than those used in traditional cross-country skiing, allowing for greater speed and agility. The skis also have special bindings that allow the athlete to quickly transition from skiing to shooting.
