Jamaican sprinter Usain Bolt and 400-metre runner Sanya Richards of the United States have won their second IAAF World Athlete of the Year awards.
Bolt retained the honour by winning the 100 and 200 metres finals in record times at the World Championships in Berlin, matching his 100 and 200 double at the 2008 Beijing Olympics. He won a third gold in the 400-metre relay.
Richards, the 2006 winner, got her first major individual gold medal at the worlds in August.
She also won at all six Golden League meetings in Europe to claim a share of the $1 million jackpot (euro673,000) offered to athletes who swept their event.
Bolt and Richards each defeated four other candidates on the shortlist voted for by nearly 1,800 athletes, officials and journalists.
