Career
Five times she came in third in the overall ranking. Besides participating in the allround championships Groenewold has participated in the championships for individual distances. Her best results there were winning the team pursuit in 2008 and the 3000 meters in 2009.
In 2002 Groenewold participated at the 2002 Winter Olympics.
Motivated by this success Groenewold was looking forward to the 1500 m but to her bitter disappointment she fell in the second turn. At the 2006 Winter Olympics, rookie compatriot Ireen Wüst beat her to the gold on the 3000 m, leaving Groenewold with silver once more.
In 2010, Groenewold competed again at the 2010 Winter Olympics, in Vancouver. She was listed as one of lesbian athletes at the Games, even though she never publicly came out and even denied she was a lesbian.
She retired from speed skating later that year.
