Rules to play Biathlon
The 20 kilometres (12 mi) individual race (15 km for women) is the oldest biathlon event; the distance is skied over five laps. The biathlete shoots four times at any shooting lane, in the order of prone, standing, prone, standing, totaling 20 targets. For each missed target a fixed penalty time, usually one minute, is added to the skiing time of the biathlete. Competitors starts are staggered, normally by 30 seconds.
