This time of year, Katrin Pardue likes to pull on her wool socks, fire up the blinkies on each shoe and run up Mount Spokane after work. Or, perhaps less ambitiously, she’ll run around the South Hill, where she lives, and take a tour of its parks: Cannon Hill, Cliff, Manito, Comstock and the Bluffs. “I try to hit every park,” said Pardue, 19, who runs between 35 and 60 miles a week. She’s preparing for Bloomsday and next fall’s Portland Marathon, but the main reason she runs is simple: She likes it.
