I've made it through the first 4 weeks - in good, but old trainers with a bit of mild knee pain. My reward for getting this far was plucking up courage to go to a running shop and getting fitted for new running shoes. First run in them and knee much better. But I've got pain on the outside of my ankle - quite sharp when walking but no swelling. I'm wondering if tendons being stretched as my gait corrected. Any idea how long I rest it? I don't want to lose momentum - I've never managed to get this far with running before and the podcasts are fantastic.
