Tracey had cancer of retina aged 4, which resulted in her losing her sight. Although a T11 runner, Tracey often has to run against T12 category athletes, who have some vision. Tracey suffered an Achilles injury after Athens Paralympics, ruling her out of competition for almost 2 years, but she won T11 400m Gold at Paralympic World Cup in Manchester on her 1st competitive race back. Beijing was Tracey’s 5th Paralympic Games.
