I think I want to try cross-country skiing.
It is a very fun sport that includes a variety of formats for their races.
Oh really, like what?
For example, there are courses of varying lengths depending on the rules sanctioned by the International Ski Federation ans by other national organizations.
Oh, very interesting. Is it a competitive thing?
Yes there are even several international competitions like the FIS Nordic World Ski Championships and the FIS Cross-Country World Cup, or even the Winter Olympics.
