According to the rules of the Brazilian federation, these are the selection criteria:
1. Athletes with the B criteria (under 300 points) in both sprint and distance have the priority, in case the number of athletes in this category is bigger than the number of available tickets (and it is), we go to;
2. A ranking is made, counting the three best sprint freestyle and three best classic distance results from July 2020 to 16 January 2022.
There was a bit of a question about which athletes would count in this 2nd one, but (as logic dictates), we have had confirmation that this ranking will decide the tickets only among athletes who have the B criteria in both sprint and distance.
Right now, that's Duda, Bruna (and Gabi, who sadly wasn't able to go to Europe) and from the next FIS points list Jaque, and those three will have so in January as well. Mika needs to have a few personal bests on sprints to get there, and then she'd be in the fight as well.
