The greatest paralympian: Tanni Grey-Thompson won a British record 11th gold medal in the 400m in Athens in 2004. The tactics of Britain's most famous Paralympian were clear by this point: she refused to talk to other athletes on competition day, and did a 'warm up lap', which she was told unsettled her rivals. But she was eclipsed by American Trischa Zorn who, aged 40, came out of retirement to compete. She won a bronze in the 100m Backstroke S12 to bring her to 46 medals from games stretching back to 1980, including 32 golds. Zorn (above) remains the most decorated Paralympian in history.
