Ashton Eaton

You see somebody on a football field make a great, athletic 70-yard run, but the athleticism is immeasurable. It's undoubtedly athletic, but compared to somebody else who did something else, how do you compare it? That's the great part of track and field. It's a test, but with results that you can compare to others.

I don't think Estonians ever really hated Russians. It was more, 'Leave us alone.' We can't change what is past. We can't blame them for what their parents have done. We never hated them. They didn't destroy us that bad.

The closer I get to retirement, the more I feel it will be a huge change, a shock, because athletics has been the core of my whole life. I know I'll miss the feeling of running fast, the adrenaline rush, and hearing the crowd cheering me on.

The Yas Marina circuit is really pretty impressive. The track itself has some quite slow corners and not a great deal of overtaking opportunities, but it seems to combine a road course with a circuit course.
