Rachel Harris-Gardiner has been researching and writing about women in motorsport since she was a student in 2001, when she first decided to look up a mysterious female Formula 1 driver called "Davinia Someone" mentioned by her father. The first version of her Speedqueens blog was published in 2004.

In 2017, she began writing professionally, having decided against an academic career. A chance meeting at a networking event led to her being accepted into the Autosport Academy training program, despite being 37 at the time.

She regularly writes for "Autosport" and "Motorsport News", covering national racing in the UK, and has a special interest in historic Formula Ford racing.

Speed Queens is her first book.
