Jahangir Khan went 555 matches without losing

Between November 1981 and November 1986, Pakistan’s Jahangir Khan played professional squash at the highest level and won every single match: 555 consecutive games, a run that lasted around five and a half years. Guinness World Records recognises it as the longest unbeaten run in men’s squash, and one of the longest winning streaks by any athlete in top-level professional sport.

Khan was 17 when the streak began. As he piled up titles, opponents arrived expecting to lose, and the few who believed otherwise rarely came close.

The run finally ended in the 1986 World Open final in Toulouse, where New Zealand’s Ross Norman - who had vowed for years that he would one day catch Khan slightly off form - beat him in four games. Even then Khan’s dominance barely dipped: he stayed unbeaten for a further nine months. He won the World Open six times and a record ten British Open titles.
