Next year's two NASCAR Sprint Cup Series events at Pocono Raceway will be shortened to 400 miles.

The races had previously been 500 miles at the 2.5-mile track in northeastern Pennsylvania.

"The 400 mile distance will make NASCAR racing at Pocono even more exciting," said Brandon Igdalsky, track president and CEO. "Race strategies will change, fuel mileage calculations will be altered and I firmly believe that our fans will be treated to outstanding racing at the 400 mile distance."

NASCAR officials support the move.

"We believe this will be a good transition for the fans and competitors," said NASCAR senior vice president for racing operations Steve O'Donnell. "It will provide the teams with a new type of strategy and should make for even more exciting competition at a unique facility that has a long-standing history in our sport."

Brad Keselowski won this past Sunday's race at Pocono.

Next year's races are scheduled for June 10 and August 5.
