'It's the best high there is' (Running)

I'm not really an athletic person, but I've never craved a good, long run so much:

I need a wide open space,
where I can run it all away
Run my way to that elation,
only exertion can bring.
I want to run and run,
away from him.
And her.
Away from myself,
and all that i feel.
I want to run and run
till my breath comes in gasps
and my muscles all cramp.
Till I can't think or feel
Anything.
Ezcept the pounding of my heart
and the blood coursing through my veins
and the sweat pouring from my body.
I want to run till I'm flying
with the wind.
Gliding along with her,
unabated.
I want to run till I'm sore
and wholly exhausted.
Till all the pain is dulled
by the ache of my body
I want to run to a high
that will push away the sorrow.
I want to run it all away,
to feel nothing.
Only hollow.
