What is biathlon?
The biathlon is combining two disciplines: cross-country skiing and rifle shooting. Biathletes alternate ski and shot (lying and standing) on 5 targets at a distance of 50 m, with a diameter of 4.5 cm for the lying shooting and 11.5 cm for standing shooting. Each shooting error is punished either by a time penalty (+ 1 min for the individual event) or a penalty loop of 150 m for other events.
