With a world championship title to go along with his Olympic gold medal, Ashton Eaton has now won all there is to win in the decathlon.

The American completed his collection on Sunday at the world championships with a season-leading total of 8,809 points in an event many consider to be the toughest there is.

"It feels good. It was the last thing I had left on my list to do," said Eaton, who rallied after a relatively sub-par first half of the two-day competition. "Now I've done everything there is to do in multi-events."
