If I don't train enough, of course I'm nervous.
If you're planning only to make money and nothing else, you'll be broke.
I used to run to school, 10k every day. And this at altitude, perfect preparation, really.
Athletes have to be confident and I am thinking like that.
I remember in particular my first victory when I achieved a very fast time in what were perfect conditions but since then the wind has always been a factor against me.
In the marathon a crazy athlete can just keep pushing from the beginning, at a championship you don't need a time just to win the race.
