I have to add the lyrics to this song, which I find so motivating (I think the song is about a relationship, but for me, it's about my old, overweight, unhappy life). It also has a great pace for running (for me).

The Afters
Never Going Back to OK
It's not the end
But it feels like it is
I'm waking up
Like I'm back from the dead
I'm stepping out
And I feel so afraid
But as long as I'm moving it's all right
I feel alive
And it hurts for a change
And looking back and
it's hard to believe
That I was cool
With the days that I wasted
complacent and tasteless
and bored but
That was yesterday
We're never going back to OK
We're never going back to easy
We're never going back to the way it was
We're never going back to OK
This discontent
Like a slap in the face
Of mediocre
I've had enough of this place
This party's over
And I'm moving away from
the frills of you Beverly
Hills but that was
yesterday
We're never going back to OK
We're never going back to easy
We're never going back to the way it was
We're never going back to OK
We're here to stay
This is our time
Our only life
Our chance to live
We're never going back to OK
We're never going back to easy
We're never going back to the way it was
We're never going back to OK
