Lap races on a loop measuring 3.3 kilometers, that was what the riders had to work with in the pursuit start over 20 kilometers in Oberstdorf in the fourth stage of the Tour de Skis.

Six laps were grazed and it is important to keep count, just ask Frida Karlsson who lost count of the laps during the race.

Didn't she know what lap she was on?

- Well, she probably just wanted to make sure of that, it was out on the fourth lap, then I said there were two laps left, so she got it then, that's how she knew when to pull away, says national team manager Anders Byström to SVT Sport .

"It's getting a little messy"

Karlsson called out to the leaders to find out which lap she was actually on.

- I shouted to all the leaders, "which lap am I on"?

It gets messy when there is so much, says Karlsson to SVT Sport.

Is it often the case that you don't have a clue?

- Yes, maybe not for everyone, but for me, says Karlsson and laughs.

In another scenario where you didn't get the right answer, could it have been costly?

- Yes, then maybe I would have finished after five laps, says Karlsson.
