Kansalliset Pentik-hiihdot is a cross-country ski race in Posio, Finland, run under the Kansalliset name. The source list shows it as an individual-start event, so racers leave one by one rather than all at once.
The available details are for the M08 race, a 2.0 km category with three young competitors on the start list. There is not much course detail here, but the format points to a small, local Finnish ski event where the focus is on age-group racing rather than a large mass start.
