Calle Halfvarsson has shown good form at the beginning of the season.

But in the opening sprint at the Tour de Ski, it was difficult for the 33-year-old.

Halfvarsson narrowly made it through the prologue and then the day ended already in the quarter-finals.

After the early exit, he was self-critical.

- I think I'm riding woefully badly downhill today.

I stand like a rake downhill and feel very unstable, he tells SVT Sport.

Starts far back in the chase start

Tomorrow the Tour de Ski continues with the hunt start.

But after today's early departure, Halfvarsson starts a little behind in the lead.

- Now you have to focus on tomorrow.

Now you are a bit behind right away, but the chase starts tomorrow and hope the starting field can pack up.
