On Friday, the tour kicks off with a freestyle sprint in Val Müstair, Switzerland.
There, the riders can earn up to 60 bonus seconds, which can be significant for the rest of the competition, which is a test of strength with eight competitions between 1 and 10 January.
- It is important for me to succeed well in the sprints.
That is perhaps the biggest challenge for me.
It is important to make a good prologue.
It is the first thing that happens tomorrow and I will try to be on my toes from the start, says Karlsson to SVT Sport from a wintry and sunny Val Müstair.
