Ashton Eaton

The first pet I remember was a cat called Baby. She would sleep with me, and I could call her from anywhere, and she would come running.

Even though decathlon is really long, there's always something different to look forward to, which is great for mental stimulation.

I would say 90 percent of the stuff we do is technical anyway. If you look at a two-hour training day, 12 minutes are probably spent running or gaining fitness.
