8x400m. Speedwork. Horrible! Why does it hurt so much? It hurts so much at the time then disappears as soon as you stop. Towards the end of the session I started to think about the psychology of pain and thought about GI Jane’s “pain is your friend!” When you break down pain of running, what is it exactly? The work of breathing so hard, the pain in the leg muscles? For me it is more my mind saying stop, it hurts, it hurts! Once you push past that, ignore your head, running becomes marginally easier. That or the fact I only had one leg of the last 400m to go, I sped up rather than slowed down.
