Getting ready for a trail race? Try this for your training:
1. Seclude yourself in a remote cave for three years.
2. Spend most of your time practicing breathing exercises and chanting Buddhist mantras.
3. Practice leaping upward from a cross-legged sitting position without using your hands. Repeat ad infinitum.
4. Return to the world three years later, light as a feather, in a heightened state of consciousness.
Run vast distances. Win races. (Known side effect: By this point in your training, the act of winning will have become meaningless to you).
