Ebba Andersson and her brother Fredrik Andersson won the three- and five-mile races at the Swedish Championships in Piteå.
So there are two strong skiers who join the long-distance race team Lager157 before the penultimate race in the season's Ski Classics.
The Reistad race is 50 kilometers long and is decided on a tough track in northern Norway.
The last time it went in Ski Classics was in 2019 and then Astrid Öyre Slind and Mikael Gunnulfsen won.
Ebba Andersson made her Ski Classics debut in Vålådalsrennet a year ago and then won immediately.
The race is broadcast on SVT1 and on SVT Play at 10.00 on Saturday.
