Martin Fourcade led after a clear shoot first time into the range however a miss on his second trip pushed him down to seventh with Russian Anton Shipulin leading the way.
Shipulin still led after a third clear shoot however Martin Fourcade was back to his best to move up to second 2.3seconds behind before retaking first place shortly after.
His margin over Shipulin became 32.4seconds by the final shoot, which saw the Frenchman go clear and the Russian miss once and fall away to eighth place overall at the finish.
