When is the big Cross Country skiing relay that has been so close in previous Olympics?

I think Norway and Finland(or Sweden) have had extremely close results in the distance Cross Country skiing relay.

Anyone else remember this? And, does anyone know when it is scheduled for this year? Are both countries still competitive?

Here’s the schedule for all the cross-country skiing events. The 4 x 10 km men’s relay is on the 24th and the 4 x 5 km women’s relay is on the 25th.
