He also won the 2005/06 Four Hills Tournament (shared with Janne Ahonen), as well as silver and bronze medals at the 2005 World Championships.

Norway's Lars Bystøl was the unexpected winner in Innsbruck while Janda finished ahead of Ahonen again to move into a two-point lead before the last competition.

After the Olympics he returned to the podium in the World Cup event (2nd place in Lahti), but his form was less solid than at the beginning of the season.

His biggest rival Janne Ahonen tried to take advantage of it, but also struggled and after disappointing Lahti results on the eve of the end of the season, he decided to withdraw from one race of the World Cup to concentrate on the last events in Norway and on mammoth hill in Planica.

Qualifying last to the final round of the first of two Planica races and finishing 29th after the second jump, he was helped by Ahonen, who did not reach a better result than 11th place.

Coach Vasja Bajc ended his relationship with the Czech team after the season and was replaced by an Austrian, Richard Schallert.

On 2 October 2017 he made his last official career jump when he stuck at the qualification round of Grand Prix season final competition in Klingenthal.
