Olympic and world women\'s wrestling champion Saori Yoshida says she is ready to compete for a record 13th straight global title, only weeks after her triumph at the London Games. \"Honestly speaking I\'m tired,\" said the 29-year-old, due to take part in the Women\'s World Wrestling Championships on September 27-29 at Sherwood Park in Alberta, Canada. \"I must go on. I don\'t know who will come. But if I get tough, I will be alright,\" she told Japanese media in Osaka on Tuesday. Yoshida won a third straight Olympic gold in the freestyle 55kg on August 9 on top of her nine world crowns, equalling the record of 12 global titles held by Russia\'s three-time Olympic Greco-Roman gold medal winner Alexander Karelin. \"I have been obsessed with consecutive wins. Once I take part, I will have only the victory on my mind. I want to surpass Karelin\'s record.\" Yoshida said Karelin, who will turn 45 next week, had given her a message of encouragement before the London Olympics through his associate, saying: \"Be confident.\" \"I am pumping myself up\" towards a training camp for the Japanese women\'s team due to start in Tokyo on Sunday, she said.
