Poor posture or other biomechanical problem. Poor shoes. Do you grit your teeth? Do you hold your arms too high with tension in your shoulders? Do you always run on tarmac?
So you could try running on varied surfaces and relaxing your running form. If not perhaps you need different shoes or orthotics.
Be bold and take a chance, what's the worst that could happen? Your hair will grow again if you don't like it. I have only one choice due to, well, err, lack of hair really; clippers.
I work for a company with about 8 fairly enthusiastic runners in. None are in a club but they would be interested if we could do it ourselves. It looks quite easy and cheap to get affiliated. Have you done it? Is it worth the effort or just a pain in the bum?
