The fastest slap shot recorded by an NHL player is 108.8 mph, made by Zdeno Chara at the 2012 all-star skills competition in Ottawa, Canada. The slap shot eclipsed Chara's old record of 105.9 mph. When Chara set the new record for the "hardest shot" competition, he claimed his fifth victory in a row for the event.
One skill shot recorded by Jared Cowen at the March 2014 all-star event hit 110.5 mph, but the puck was made of foam and not vulcanized rubber. Cowen was victimized by a prankster with access to the pucks at the event.
