If you haven't tracked one down yet, I can recommend my physio who is Alex Hill at Simone Olds Associates, 'phone number 020 8788 2471. They are actually in SW15 at the top of Dover House Road (although moving in a couple of weeks to junction of Upper Richmond Road and West Hill). She's an Aussie who seems to know what she's talking about, and knows that not running is the last resort. She's keeping me in one piece for the marathon.
