I'm in Wk8R2, so pretty far along. I haven't felt any pain so far while doing the plan except for the usual bit of stiffness. I can honestly say it's changed my life. But today I felt a slight twinge in my left ankle along the outside while I was running and it has persisted for the day. Any idea what this could be? I have alright trainers (basic asics - fairly new), but admit that I haven't done a gait analysis as when I started the programme I assumed I would give up like I have with every sport I have ever tried so didn't want to spend too much money on it. Advice on what to do? This has been a real mental and physical struggle for me and I'm desperate not to have to quit so close to the end.
