It's not. Its all a lie. What it's really about...are you ready:
Shedding the thin shell of your 'being' and finding yourself. Realizing that 'other' voice was right. You are rad and strong and wonderful. It's about the sweat, tears and laughter that is shared. You becoming better, fitter. Your heart strong. Your sweat earned. Time to yourself. Reflection. Pounding on the road, trail, mountain, pasture.
Your world is turned on.
It is really, well for me, about is escape, freedom and getting out of the way of myself, to find out the person I want to be, and get my body to do what it was made to do.
