On January 17, 1992, he took third place on the Hahnenkamm run in Kitzbühel ; this was the first of a total of two podium places. Gigandet was regularly among the top ten in the World Cup, but it was never enough to win. At the 1992 Winter Olympics , he was eighth in the combination. He achieved his best World Cup placement on December 16, 1995 when he finished second on the Saslong in Val Gardena .
At the end of the 1997/98 season Gigandet resigned from top-class sport. He turned down Swiss-Ski's offer to work as a junior trainer. Instead, he and his three siblings took over their father's company, a mechanical workshop for agricultural machines.
