I think there was a 30k individual a couple of years back in Beitostolen, but anyway I definitely agree and that there should at the vey least be 2 of them each year.
Yep, my bad, the 30km and 15km in Beitostølen in December 2018 were individual starts. The sprints, team sprints, skiathlons, and relays are all mass starts. It wouldn’t hurt at all to mix things up. When will Holmenkollen go back to an individual start? I’ve heard soon. Hopefully sooner rather than later.
