Despite several respectable performances in the World Cup, Fak's performance at the Biathlon World Championships 2009 came as a huge surprise. In the opening sprint race Fak improved his career best performance by two more places by finishing 14th. However, he couldn't improve on that performance in the pursuit falling back to 25th place. The big surprise came in the 20 kilometres individual race where Fak won the bronze medal. A perfect score in the final range would have brought Fak a gold medal, however after one miss Fak had to battle very hard for at least some medal and in the end beat Simon Fourcade by less than a second to win the bronze. Thus Jakov Fak won Croatia their first-ever World Championship medal in biathlon.
