Career

While her Sprint Championships were successful when she finished in 6th position her Olympics were disappointing.
Gerritsen qualified in two distances.
She finished 12th in the 500 m and 23rd in the 1000 m. 2006-2007 season
In the 2006-2007 pre-season Gerritsen showed her potential to become the fastest Dutch sprint speed skater when beating team mate Marianne Timmer several times.
However at the 2007 KNSB Dutch Single Distance Championships she was unable to keep her pre-season form and only finished in third position behind the surprising Margot Boer and Timmer. Her performances gave her the opportunity to participate in the 2007 World Sprint Championships, where she finished 7th overall, with a 4th place in the second 1000 m race.
Her victory guaranteed her a spot in the 500 m at the 2007 World Single Distance Championship, to be held in Salt Lake City on 10 March.
Gerritsen used to date multiple Olympic speed skating medallist Sven Kramer. 2010 Olympics.
