Martin Johnsrud Sundby won one Ski Classic, Theresa J also. None of the WC sprint specialists can win, and also those who are better at skate. Astrid Slind started with Ski Classics..so some of the top WC athletes could win, but definitely not most of them.
Do you even believe yourself that you know what you are talking about here?
Let's start with
Astrid Øyre Slind, which you claim "
started with Ski Classics". As far as I know she started doing Ski Classics in the 2016 season, at the age around 27 and went went top 7 in Marcialonga, Vasaloppet and Birken on first attempt. Long before that she had already done 20+ World Cup starts and was U23 World Champion. She only switched to Ski Classics after stagnating and doing a couple of season on the Scandinavian Cup scene.
Sundby and Johaug have "only" won Birken because it is the only one they did a couple of times when in their prime. Both won with huge margins at the end of long WC seasons. Sundby's "attempt" in the Ski Classic scene in 2022 as a 37 year old with massive back issues doesnt hold much negative weight in my opinion.
When you say that "
None of the WC sprint specialists can win" it also clearly shows that you dont know much about the history of Ski Classics in the last 10-15 years and that WC Sprinters are very well suited to transform into good Ski Classics athletes.
John Kristian Dahl was a great World Cup sprinter for almost 10 years, with several World Cup wins and podiums. When he didnt qualify for the National Team no more he changed to Ski Classics and won Vasaloppet 3 times.
Johan Kjölstad was also for a long time a member of the Norwegian Sprint team with Dahl, with World Champs silver in 2009. When he got dropped for the National Team he changed to Ski Classics and won the Ski Classics overall in 2014.
Andreas Nygaard is maybe the most legendary Ski Classics athlete. He was for a long time a warrior on the Scan Cup level, with some good sprint results and even managed to qualify for a World Cup in classic sprint. Then he went from being a mediocre sprinter at national level to legend in Ski Classics. One of the better Ski Classics athletes nowaday, the Marcialonga winner of this season is
Kasper Stadaas. He was for many years a pure sprint specialist, just outside national team level and managed to qualify for cirka 15 World Cup sprints. After transitioning into the Ski Classics scene he's shown once again that the skill set needed for World Cup sprints are very compatible with the skill set needed for long races double poling.
With the history of athletes like Dahl, Kjölstad and Stadaas I belive when looking at the World Cup Overall in the sprint cup on the mens side for this season that maybe 15 of the top 20 could quite easily translate into top Ski Classics skiers within 1 season of specific focus. Im thinking Kläbo, Valnes, Vike, Heggen, Anger, Chappaz, Grahn, Amundsen, Ogden, Schumacher are the obvious picks. But also Evensen, Even Northug, Joni Mäki, Emil Liekari and Ondrej Cerny should fit the bill. Stadaas and Kjölstad are prime examples that the lack of endurance that made then pure sprint specialists at WC level isnt a problem at Ski Classics level.
