Janne Petteri Ahonen ( pronunciation (help·info)) (born May 11, 1977 in Lahti, Finland) is a former Finnish ski jumper who competed in the World Cup between 1992 and 2011. He is often considered as one of the most successful athletes in the history of ski jumping.

Ahonen's most notable achievements include five World Championships (normal hill 1997, large hill 2005, team large hill 1995, 1997 and 2003), two World Cup overall victories (2002-2003 and 2004-2005) and a record-breaking five victories in the Four Hills Tournament (1998-1999, 2002-2003, 2004-2005, 2005-2006 and 2007-2008). He is the all-time leader in World Cup points, podiums (108) and Top 10 appearances (245). With 36 World Cup victories, Ahonen is the all-time third, behind Matti Nykänen (46) and Adam Małysz (39). In 2005, Ahonen was named the Finnish Sports Personality of the Year.

In 9 World Ski Championship Games, 9 Ski-Flying World Championship Games and 5 Olympic Games, Ahonen won a total of 19 medals, equalling the medal count of Matti Nykänen. Despite his success, Ahonen never won an individual Olympic medal placing 4th three times. In Olympic team competitions, he won two silver medals.

Jakub Janda (Czech pronunciation: [ˈjakup ˈjanda]) (born April 27, 1978 in Čeladná) is a Czech ski jumper, winner of 2005-6 Four Hills Tournament and winner of the Ski jumping World Cup 2005–6.

He entered Ski jumping World Cup in 1996, but his first major success was third place in Liberec (2003). Janda improved his performance under new Slovenian coach Vasja Bajc in 2004. In 2004/5 season he managed to collect several second and third places and one victory in World Cup events. He also gained a silver and a bronze medal at the 2005 FIS Nordic World Ski Championships in Oberstdorf.

Janda started 2005-6 season with World Cup wins in Kuusamo, Lillehammer, Harrachov and Engelberg, and entered the Four Hills Tournament leading the World Cup standings. In the opening event in Oberstdorf, Janda finished in third place to place high for the second round, with Janne Ahonen in first and Roar Ljøkelsøy in second. After winning the second race of the Tournament in Garmisch-Partenkirchen, Janda moved to second place in the standings behind the reigning Tournament champion Ahonen. Norway's Lars Bystøl was the unexpected winner in Innsbruck while Janda finished ahead of Ahonen for the second straight time to move into a two-point lead before the last competition. Like in all previous rounds Janda advanced in last place into the competition to having skis that were too long during Oberstdorf qualifying and could not participate in the next three qualifying rounds as a result. The tournament climaxed with a Janda vs. Ahonen knockout duel. Janda won the first round by one point (tied to Ahonen on meters), then increased his lead to three points before the last jump. Ahonen beat Janda in the last jump by 141.5 meters to 139 meters and won the Bischofshofen competition by two points. The overall standings thus had both jumpers tied for first place, the first ever joint victors in the history of the tournament. Norway's Ljøkelsøy finished third.
