I had this thought, do Norwegian biathletes that are regulars on the World Cup ever retire without getting a single win or a podium? So I did some research
Lars Helge Birkeland has announced his retirement this year and he hasn't even been on the podium ever.
Don't know if she was much of a regular, but Thekla Brun-Lie retired in 2019/20 season without getting on the podium either.
2017/18 season Hilde Fenne and Kaia Woen Nicolaisen retired with 8th place as their best result
Elise Ringen in 2015/16 season with best placement as 10th
Rune Brattsveen in 2013/14, had a relay gold from World Championships, but PB is 5th
And that's all I got from 2010/11 to 2020/21
So if you acually get on the Norwegian team, it's pretty likely that you'll be able to podium and even win.
Some of the recent Norwegian retirements included: Solemdal, Tora and Lars Berger, Flatland, Os, Svendsen, Bjoerndalen, Andresen, Fanny Horn Birkeland, L'Abee Lund.
