Mass start 60

Starting in the 2018/2019 season, the Mass Start 60 became part of the International Biathlon Union (IBU) competition formats. The Mass Start with 60 starters does not replace the current Mass Start with 30 starters.

Everyone skis the first lap together, but only the first 30 stop to shoot, and the second 30 keep skiing. At the end of the second lap, the second 30 stop to shoot, and the first 30 continue to ski. After the first two shoots are over (everyone's first prone), the race continues like a typical race, and all competitors shoot remaining prone, and two stands together. Or more simply:

Bib 1–30 = lap, shoot1, lap, lap, shoot2, lap, shoot3, lap, shoot4, lap

Bib 31–60 = lap, lap, shoot1, lap, shoot2, lap, shoot3, lap, shoot4, lap
