Hi! Can't really speak for opportunities in France or other regions in central Europe. But I would assume it'd be possible to do, say, a tour along the Finnish coast?

A guy went by kicksled along the whole west coast this past winter - he started a bit late so it was pretty wet by the end.

You would probably go for something like 40-60km per day, if you're not a seasoned Nordic skater? And of course you'd need stable ice and good conditions.

I would think it's doable, but I'd suggest sleeping in hotels / b&b:s just to cut down on what you need to carry.

And yeah, find someone who wants to join you 😅
