FOUNTAIN, Colo. (AP) -- Greg Biffle made fast work of the Salute to the Troops 250.

Racing in both Colorado and Pennsylvania this weekend, Biffle went from last to first Saturday at Pikes Peak to win his fourth Busch Series race of the season.

Biffle, driving full-time on both the Busch and Nextel Cup Series, started at the back of the field because he did not qualify his car for the Busch Series race because of the Nextel Cup event in the Poconos.

He took control after a caution period on Lap 215, climbing from 11th to pass Jason Leffler on Lap 228. Biffle made the strong late run after patiently waiting for a good time to use his final set of tires.

"I just rode around there for a while," Biffle said. "I just had to wait for a caution, then I was going to race hard. We played strategy today." More
