As an amateur she won several events including the 2004 and 2005 English Girls' Championship, the 2006 and 2007 Helen Holm Trophy, the 2007 St Rule Trophy, and the 2007 Ladies' British Open Amateur Stroke Play Championship.

Reid failed to earn her card at the 2007 LET Qualifying School in Italy but turned professional in late 2007 and began playing on the Ladies European Tour in 2008 on sponsor invitations.

A third-place finish at the Australian Open in early February allowed her to stay in the top 20 on the money list and gain entrance into LET events for the rest of the season.

In May 2012 Reid's mother, Joy, was killed in an automobile crash near Munich while travelling to see her daughter compete in a Ladies European Tour event.

Reid quickly returned to golf but her performance declined rapidly in the ensuing years.
