How a para biathlon race works

1. Para biathlon combines cross-country skiing with shooting an air rifle at five targets 10 m away.
2. Athletes race as vision impaired, standing or sitting. Vision impaired athletes use an electronic rifle that turns their aim into a tone in their earphones.
3. Each missed target costs a penalty loop, skied straight after the shooting, or added time in the individual.
4. A percentage for each athlete's class turns their skiing time into a calculated time, so all classes race together. The lowest time wins.

How long

The sprint is 7.5 km with two shooting bouts; the individual is 12.5 km with four.
