Early years
Marianne Vos was born in 's-Hertogenbosch, North Brabant and lives in the small village of Babyloniënbroek. She started her career when she was six years old after watching her older brother who was already a cyclist. At first she trained with her brother's team as she was not allowed to participate in races; during the winter she started training in cyclo-cross as well. When she was eight, she was able to ride races. Vos also participated in speed skating and inline speed skating. At 14 she replaced inline skating with mountain biking.

Including Vos's world championship in 2004 the Netherlands had won the last three editions of the junior championship (the others being Loes Markerink in 2002 and Suzanne de Goede in 2003). Vos's goal was to add a fourth title by defending her title in Salzburg, but she finished second behind Denmark's Mie Bekker Lacota.
