he was concerned about youngsters ending up the same situation. He also defended his links with Christie, stating that he would not have remained with Christie if he thought he had cheated. Retirement Campbell announced his retirement on 18 August 2006. His final race was at the inaugural Celtic Cup race in Grangemouth, where he won the 100 m competing as a guest. Campbell surprised Dave Collins and UK Athletics, who had been expecting him to retire following the two-day international athletics meeting at Birmingham taking place over the following two days. In July 2007, Campbell was announced as the new ambassador for Sky Sports Living for Sport, a successful initiative run by the Youth Sport Trust in conjunction with BSkyB, which uses sport as a tool to re-engage young people who may be at risk of opting out of school life. Sky Sports Living for Sport, now in its fifth year, has involved over 600 schools and benefited over 17,000 young people aged 11–16. Campbell's role will see him meet young people and teachers involved in Sky Sports Living for Sport across the country to share his experiences and help inspire them to reach their full potential.
