Block was identified by Victor Conte as allegedly having taken illegal performance-enhancing drugs supplied by Conte in the BALCO scandal. In 2011, she was handed a two-year ban from sports for doping, and her results from 30 November 2002 onwards were disqualified. Her husband and coach, Mark Block, was given a 10-year ban from sport for supplying his wife with performance-enhancing drugs.
She took part in the 100 and 200 metres races at both the 1996 Summer Olympics and the 2000 Summer Olympics, reaching the final three times. She also took part in the 100 m and 4 x 100 metres relay at the 2004 Olympics. However, she failed to progress to the finals. She has never won an Olympic medal but she managed to finish in fourth place in the 100 m final in Sydney. Her 100 metres personal best time of 10.82 seconds was set in Edmonton, Alberta, Canada on 6 August 2001.
