Kallur made a breakthrough by winning the 100 m hurdles at the 2000 World Junior Championships held in Santiago, Chile. She then initially failed to make an impact on senior competition, failing to make the final of two World Championships and then the 2004 Olympic Games in Athens, where she improved her personal best to 12.67 seconds.[1]
Kallur retained her title at the 2007 European Indoor Championships in Birmingham. She finished only fourth in the 100 m hurdles at the 2007 World Championships held in Osaka, despite running a personal best of 12.51 s and having a clear lead to the final hurdle. The Swedish team had grounds for appeal, as eventual winner Michelle Perry had crossed over into Kallur's lane, possibly interfering. But by the time they did register an appeal, the time limit had elapsed.[3][4] After the World Championships, Kallur won the three remaining Golden League events in Berlin, Zürich and Brussels, posting a personal best in the German capital and beating Perry in all three races.
World record and injuries
After posting several fast times throughout the beginning of the 2008 indoor season, Kallur broke the 60 m hurdles world indoor record with a time of 7.68 seconds at a meeting in Karlsruhe, Germany on 10 February. She was then the clear favourite for the World Indoor title in Valencia, Spain and won her heat in 7.87 seconds, but did not start the semi-finals, pulling out injured.
She fell at the first hurdle of her semi-final of the 100 m women's hurdles event at the 2008 Olympic Games in Beijing. She missed the entirety of the 2009 season through a stress fracture injury. She had surgery on her shin in late 2008 and, although she had a metal plate removed in June 2009, she declared herself unfit for the 2009 World Championships.[5]
She briefly returned to competition in 2010 running a time of 12.78 s in New York City to finish seventh and coming fourth over 100 m hurdles in the first division of the European Cup. However, she was again sidelined from athletics in 2011. She had hoped to compete at the World Championships but did not recover from injury in time. She resumed training in August at a low-intensity, with the aim of competing in the Olympics in 2012.[6]
In March 2017, she competed in European Indoor Championships held in Belgrade, Serbia.[7] She reached the final in 60 m hurdles and finished eighth with a time of 8.14 seconds as her last match before retirement.[8]
She is 1.70 metres (5 ft 7 in) tall and weighs 61 kilograms (134 lb; 9 st 8 lb). She was coached by Torbjörn Eriksson and also by Karin Torneklint.[9] Often called 'Sanna' in Sweden.
