Running is free, it's simple and it's what you want it to be. I don't think running is special, very enjoyable and addictive, but doing the most natural thing in the world is not special.
I can recognise that other peoples achievements (that may mean nothing to me) are special and personal to those people, and what is an achievement to me may mean nothing to anyone else. So whether your marathon is 2 hours or 6, it shouldn't matter.
