Shazza, watch the stretchin - I used to stretch a lot, but was (apparently) trying 'developmental' streches at the wrong time, so ended up with more injuries. I also suffered increadable muscle stiffness, was advised by a friend to try cold showers on my legs and low back. So after these changes I've gone from being able to run for approx 2 months per year to a regular 15 to 20 miles per week for the last ten months, mixed with swimming, squash, cycling and gym work when I can fit them in, and I'm hoping for the chance to run a few races next year for the first time in ten years...
