He did a little more than that, but still ran away with the second annual Twilight River Run Friday night in 15 minutes, 15 seconds -- 22 seconds ahead of second-place finisher Andy Passmore.
"I knew he was playing with me," said Passmore, 30, on a comeback of sorts after he and his wife had a child 14 months ago. "Coming off a 24:15 over the weekend [in the Bon Ton 5-miler in York, Pa.], he was just doing what he had to do. He's the class of the area -- has been for a long time."
On a comeback from an inflamed bursa in his knee, Clapper would not say he was playing with anyone.
"I still feel it," Clapper, 30, said. "In fact, this week I felt it a little more with all the racing. I'm just trying to get the mileage up. That's the hard part.
"Andy really pushed the pace through two miles," said Clapper, who had mile splits of 4:54 and 9:57. "But I could see that he was pretty well spent and thought it was time to pick up the pace.
"I ran the Bon Ton and then the mile race [Howard County Striders' Meet of Miles] Wednesday night so I was feeling it a little more."
