The Norwegian powerhouse, who leads the discipline standings after the opening four races, crossed the finish line in 1 minute, 50.92 seconds.
Italian Werner Heel finished second, 0.05 seconds behind Svindal while Kjetil Jansrud was third, .36 second off his team-mate’s pace.
The 78 racers did not practice on the longest course on the men’s circuit as variable weather prompted organisers to start the training run from the Combined start.
There are two more training runs before Friday’s Super Combined followed by Saturday’s downhill, won last year by the Swiss Beat Feuz who is absent due to injury.
Meanwhile, because of large amounts of new snow the first training run for the women's World Cup downhill in Cortina d'Ampezzo on Thursday has been cancelled.
