Doucouré was eliminated in the 110m hurdles semi-finals of the 2007 World Championships. Doucouré finished fourth in the final of the 110 m hurdles (his only event) at the 2008 Olympics in Beijing. The following year, he started strongly by winning the 60 m hurdles gold medal at the 2009 European Indoor Championships. At the 2012 Olympics in London, he finished last in his semi-final heat of the 110m hurdles – the only event that he entered – and thus did not qualify for the final.
