BRISTOL, Tenn. — They got their father’s love of speed, but the annual trip to Bristol Dragway for the NHRA Fitzgerald USA Thunder Valley Nationals is a time when the racing Force sisters can also celebrate 16-time Funny Car world champion John Force simply as their dad. Courtney Force gave her best imitation of her father on the track Friday night with her run of 3.993 seconds at 325.92 mph, easily the best time in the qualifying session.
