JOINT BASE MYER-HENDERSON HALL, Va. - A frosty feel was in the pre-dawn Military District of Washington air when 118 runners scampered clear of Henderson Hall's Cpl. Terry L. Smith Gymnasium Devil Dog 7k starting line Sept. 18.

Less than a half hour and 4.3 miles later, Marine Capt. Justin Kirk was the first to cross the Devil Dog 7k finish line.

The Pentagon-based service member knocked his early morning run out of the way in a time of 25 minutes and 13 seconds. Kirk's Semper Fit Oohrah Series jaunt was a part of his return to competitive running after a layoff due to injury.

"I really don't know my pace right now," said Kirk, who is rehabilitating from an achilles injury. "I definitely paced myself; I didn't go out too hard, which was good this morning. This is kind of an unknown distance, 7k, it's a pretty weird distance, so it's hard for me to calculate what my actual pace could have been. I know it was under six minutes [per mile], which is fine."

Two JBM-HH road race veterans also posted top three times for the race, which traversed length-wise through the joint base to eventually turnaround at the Marine Corps Memorial. Yuko Whitestone was the women's winner in 31:14, and Joseph Galvin was male runner-up with a clocking of 25:23.

Gabby Pasillas (34:18) was the second woman to cross the finish line, and Christy Gunville was third in 36:02. The men's third-place finisher was Daniel Richard in 27:20.

Prior to the road race, the Semper Fit Oorah staff led all runners and spectators in a moment of silence in remembrance of the victims, families and survivors of the Washington Navy Yard shooting.
