In January 2006 Groothuis surprised by becoming the Dutch national sprint champion finishing in first position after two races over 500 metres as well as two over 1000 metres, outsprinting common names like Gerard van Velde, Nijenhuis and Wennemars. A month later at the 2006 Winter Olympics Groothuis would finish in 8th position over 1000 metres. His time of 1:09.57 was 0.68 behind on winner Shani Davis.
