Justine Braisaz-Bouchet kept it together from her lead and with just one boom she was able to go out with a 48 second lead to Tiril Eckhoff and take a sure victory.
Elvira Öberg did not have the day on the track and lost steadily in skiing.
Before the last shot, Elvira Öberg was 17.2 seconds behind leading Braisaz-Bouchet and 1.7 seconds behind second Marte Olsbu Röiseland.
Öberg was there in fifth place in the dense field.
The Frenchwoman took a French flag and went to the finish line as a superior winner.
In the third shot, the first in standing, it had blown up properly and the Norwegians Marte Olsbu Röiseland and Tiril Eckhoff were loose but they did not dare to come to shots and pulled on two booms were after standing on the embankment in 1.07 and 1.20.
It sealed the field.
Elvira Öberg, who started with a boom in the first lying, shot full for the second shooter in a row and was suddenly in the gold battle when she went out as third just five seconds behind leading Röiseland, who had Justine Braisaz-Bouchet in an even close.
