Marathon song

I, RS, have neglected an important decision four weeks into my 20-week marathon training. I need to select rslight's official 2007 Chicago Marathon training song.

I really like "Resolve" by Foo Fighters. However, it is difficult to resist "Let's Get It Started" by Black Eyed Peas.

I've already adopted my official 2007 Chicago Marathon training motto. It comes from the recent film 300, which I loved. Prepare for glory!
