About halfway into the men's mass start in Antholz, a then faultless Sebastian Samuelsson sniffed a top position.

But he got stuck in a track marker.

- I lost a little there, says Sebastian Samuelsson.

Watch the event in the player above.

Samuelsson missed only two shots.

But he crossed the finish line 45 seconds and twelve places behind seventh-placed Jesper Nelin, who also had two misses.

- I was a bit stubborn.

I think my stomach is starting to bubble a little too, I know there has been food poisoning at our hotel.

It is not so good.

- It's not that dangerous, but I feel like it's starting to bubble a little.

The Biathlon World Cup begins on the seventh of February.
