If I don't train enough, of course I'm nervous.

I always tell young athletes the same thing, 'Wherever you go, whatever you do, what must your top priority be? Running.'

The more you are getting older, you lose a little something. Of course there is another advantage, because of your long experience you can use it.

You need three things to win: discipline, hard work and, before everything maybe, commitment. No one will make it without those three. Sport teaches you that.

If your body is damaged, wounded, it can be fixed, but if inside, mentally, you are wounded you cannot fix it, it's hard.
