The mixed relay made its debut at the 2014 Sochi Olympic Winter Games. Two men and two women compete on each mixed relay team, which is simply four sprint-style legs. The same genders start consecutively; if the women lead off the distance is four 6 km legs (3 x 2 km with prone and standing shooting stages), if the men lead off, then it is four 7.5 km legs (3 x 2.5 km with prone and standing shooting stages). In each shooting stage, the competitor is allowed to use three spare rounds if needed to close their five targets. A 150-meter penalty loop is run for any unclosed targets after the eighth shot is fired. Exchanges between each leg are a tap of the shoulder from the incoming athlete to the outgoing athlete. The first team to cross the finish line is the winner.
