The American-based Air Race Classic is an air race for women that began as far back as 1929 as the "Women's Air Derby" and featured the legendary Amelia Earhart.
That first race saw female pilots race planes from California to Ohio and has continued as an annual trans-continental event.
After an interruption during the Second World War, the race continued as the All-Women's Transcontinental Air Race which lasted until 1977. It was then picked up by another group and continued under the name of the Air Race Classic.
