Thursday in Hayward, the fun before the Birkie.
The race is this weekend but there's plenty to do for the whole family ahead of time.
Nordic skiers and spectators were able to stop by the Birkie Expo, which opened Thursday afternoon.
Also on Thursday -- the Barkie Birkie, the Junior Birkie and the Birkie Bash pasta buffet.
Organizers say the energy at this year's event has been a big change from last year because there's so much more snow.
"The ski conditions are going to be really good both Friday and Saturday. It's going to bring really fast conditions but then it's also fun to be outside spectating," said American Birkebeiner Executive Director Ben Popp.
The big race begins at 8:15 Saturday morning.
