Coroner James Kelley says preliminary tests show Michael Kenney died as a result of drowning.
The body of the 55-year-old was found in Weiser State Forest, about half a mile from his car.
Kenney was an avid runner and was training in the forest last Wednesday, but he never came home.
Kelley says there are no signs of foul play.
Wednesday night, family and friends attended a prayer service in honor of Kenney.
