The 2008-09 Biathlon World Cup/Pursuit Men started at Sunday December 7, 2008 in Östersund and will finish Saturday March 28, 2009 in Khanty-Mansiysk. Defending titlist is Ole Einar Bjørndalen of Norway.
In a pursuit, biathletes' starts are separated by their time differences from a previous race, most commonly a sprint. The contestant crossing the finish line first is the winner. The distance is 12.5 kilometres (7.8 mi), skied over five laps; there are four shooting bouts (two prone, two standing, in that order), and each miss means a penalty loop of 150 m. To prevent awkward and/or dangerous crowding of the skiing loops, and overcapacity at the shooting range, World Cup Pursuits are held with only the 60 top ranking biathletes after the preceding race. The biathletes shoot (on a first-come, first-served basis) at the lane corresponding to the position they arrived for all shooting bouts.
