Visma Ski Classics is just around the corner and now we have the start lists for the Orsa Grönklitt races this Saturday and Sunday, but not without some mystery.

Marit Björgen will be on the start line, but who is Mrs. X? 

Rumor says that she is another Olympic gold medalist. Is it true? And is she really from Norway?

You can check Saturday’s Pro Team Tempo start lists clicking here and Sunday’s Individual Prologue start lists here.

Now, if you’ve looked through all the start lists and still don’t know who Mrs. X is, come back at Pro XC Skiing on Friday and find out!
