Ashton Eaton breaks world record as he wins decathlon gold [...] Eaton gritted his teeth and charged ahead, grimacing as he stepped over a low railing and into the stands to wrap his exhausted arms around his wife. With an all-out run in the final event, the 1,500 meters, Eaton finished the two-day event with 9,045 points on Saturday at the world championships. The 27-year-old Eaton hasn't completed a full decathlon since capturing the world title in Moscow two years ago. [...] in the 10th and final event, with his Achilles and knee throbbing and the record within reach, he went for it. On the first day, he broke the world-record time for the 400-meter decathlon event, finishing in 45.00 and eclipsing the old mark he shared with 1968 Olympic champion Bill Toomey by .68 seconds. Shortly after hugging his wife, Eaton ever-so-slowly made his way over for pictures in front of the on-track display flashing his world-record score in yellow letters. Because that's the only thing to do.
