100 Team GB contenders for London 2012: Katherine Grainger
Rowing (double scull)
Born : 12/07/75
Grainger is Britain's most successful female rower, with silver medals at each of the last three Olympics.
She won the double sculls with Anna Watkins at the 2010 and 2011 World Championships, and now boasts six world titles after winning the coxless pair (2003) and the quadruple sculls (2005-2007).
- 2008 - Silver in quad sculls
- 2004 - Silver in pair
- 2000 - Silver in quad sculls
She and her quad sculls team-mates went into the 2008 Olympics having won the previous three World Championships but had to settle for silver behind the Chinese quartet.
A distraught Grainger considered retiring but decided to continue in the hope of landing the elusive gold in London in 2012.
The Scot, who took up rowing while studying law at Edinburgh University in 1993, has a black belt in karate and is currently studying for a PhD in in homicide.
She told the BBC: "I watch everything from Murder She Wrote to Law & Order, CSI, Sherlock. I pretend it's work, so if I haven't been to the library or written many chapters, I think 'At least I put some hours in watching those educational programmes'."
