2004–05 Four Hills Tournament
The 53rd edition of the annual Four Hills Tournament was held in the traditional venues: Oberstorf and Garmisch-Partenkirchen in Germany, and Innsbruck and Bischofshofen in Austria.
The Four Hills tournament counts as part of the World Cup season. Before the competition in Oberstorf, eight out of twenty-eight events were already held. Janne Ahonen had won seven of them, and placed second in the only one he did not. This early-season dominance of the Finnish athlete, who had already won the Four Hills tournament twice before, made him the favourite for the title, and Ahonen did not disappoint. He won the first three events, though he failed to become the second ski jumper after Sven Hannawald to win all four events of the tournament when runners-up Martin Höllwarth snatched the victory at the final event in Bischofshofen.
Format
At each of the four events, a qualification round would be held. The 50 best jumpers would qualify for the competition. The fifteen athletes leading the World Cup at the time would qualify automatically. In case of an omitted qualification or a result that would normally result in elimination, they would instead qualify as 50th.Unlike the procedure at normal World Cup events, the 50 qualified athletes would be paired up for the first round of the final event, with the winner qualifying for the second round. The rounds start with the duel between #26 and #25 from the qualification round, followed by #27 vs #24, up to #50 vs #1. The five best duel losers, so-called 'Lucky Losers' also qualify for the second round.
For the tournament ranking, the total points earned from each jump are added together. The World Cup points collected during the four events are disregarded in this ranking.
