Christian raced at the Looper Speedway, the former racetrack which now lies beneath the waters of Lake Lanier. She won at least one race there while driving a car belonging to racetrack owner Max Looper. Edwin Looper, Max’s nephew and former employee, recalled that Christian’s victory “made all the men mad too, her being a woman and all, and winning the race.”
1949
Christian competed in NASCAR's first race on June 19, 1949 at Charlotte Speedway. She qualified 13th in the #71 Ford owned by her husband Frank Christian. During the race, Bob Flock took over her car after his engine expired on the 38th lap. He drove the car until it overheated, and finished 14th. Christian competed in the second race at the Daytona Beach Road Course on July 10, 1949, and finished 18th. The 28 car field also included Flock's sister Ethel Mobley and Louise Smith, which made it the first race to include three woman drivers. Frank also competed in the race and finished sixth in his only career start. They became the only married couple to compete in a NASCAR race until 1986 when Patty Moise and Elton Sawyer competed for the first time together in the NASCAR Busch Grand National Series. Patty and Elton were married in 1990 and continued to compete against one another for years. Christian finished sixth at the fourth race at Langhorne Speedway, and became the first woman to earn a Top 10 finish. Race winner Curtis Turner invited Christian to join him in victory lane. Mobley and Smith again competed against Christian in the race, and it was the last NASCAR race to have three woman drivers until July 4, 1977 when Janet Guthrie, Christine Beckers and Lella Lombardi all competed in the Firecracker 400. Christian finished fifth at the ninth race at Heidelberg Raceway in Pittsburgh, Pennsylvania. The finish was the best-ever and only Top 5 finish by a woman in NASCAR series history, though on a regional series level it was eclipsed by Shawna Robinson at the New Asheville Speedway on June 10, 1988, when she won the Charlotte-Daytona Dash AC-Delco 100 to become the first woman to win a NASCAR touring series race. Christian's fifth place remains the highest finish by a woman at the Premiership, now known as the Monster Energy NASCAR Cup Series. Christian raced in six of the eight events in the 1949 season, and finished 13th in the final points standings.
1950
Christian competed in one event in 1950, finishing 14th at the 12th race at the Hamburg Speedway before she retired.
