Corine Stam-Dorland (née Dorland) (born 30 June 1973 in Loenen, Gelderland) was a Dutch amateur "Old School" Bicycle Motocross (BMX) racer whose prime competitive years were from 1981-1996.  From 1996 to 2006 she was also an accomplished Mountain Bike (MTB) Cyclo-cross and Road Bike racer.  Her nickname during her BMX career was "The Queen of BMX", largely for her nearly unbroken streak of a total of ten World Champions, several European Championships and an almost equal number of National championships from when she was eight years old until she was 21.  She was to Holland and European BMX as a whole as Cheri Elliott was to American BMX.  Indeed, her career was much longer than Elliott's garnering far more titles on the local, national and international level than her near contemporary American counterpart (Dorland is three years younger than Elliott).  Dorland would go on to a respected MTB cross country (XC) racing career.  In that sub-discipline Dorland would capture three national titles in MTB and earn a spot on Holland's 2000 Sydney, Australia Olympic team.  She also went on to fulfill a prediction that many had made for her in another area.  Because of her stunning physical beauty, she was also a model in her adult years concurrent with her MTB career.  She appeared in many racing related advertisements.  As with Elliott in the United States, many a male BMXer was sad to see her retire from the world of BMX.
