The Relay (4 x 7.5 km for men; 4 x 6 km for women) is the second-oldest biathlon competition, introduced at the 1968 Grenoble Olympic Winter Games. Each relay team runs four legs with the distance based on gender (each men’s leg is 3 X 2.5 km with prone and standing shooting stages; Each women’s leg is 3 X 2 km with prone and standing 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 across the finish line is the winner.
