The long-distance skiing world championship, Visma Ski Classics, launches The Grand Classics Events, if an athlete wins all four in the same season he or she completes a Grand Slam. The Grand Classics events are the four largest and most prestigious events in the Pro Tour: Marcialonga, Jizerska Padesatka, Vasaloppet, and Birkenbeinerrennet.
No one has won all four races in the same year at any time before, completing a Grand Slam. Who will be the first?
An interesting conclusion is that no athlete throughout history has managed to win all four events during the same season, completing a Grand Slam. Swedish Sven Åke Lundbäck in 1981 and Italian Cristina Paluselli 2005 and 2006 have been the closest so far winning three Grand Classics events in one season.
A curious fact is that. The Aukland brothers together won all four in 2013, two each, but of course, that doesn't count...
It will now be great prestige to win all four events in the same season and be the first to complete a Grand Slam.
