What is biathlon?

Response:
Biathlon is a winter sport that mixes nordic skying and shooting. Depending on the format, athletes ski a loop 3 or 5 times, and shoot 5 targets between each. The targets are 50 meters away. For each missed target, the participant will ski one 150 meter long penalty loop. The winner is the athlete who completes the 3 or 5 loops first.
