Hello, first poster and very new runner.
I am a middle aged, overweight woman who has never run in her life till now. Inspired by my grown up kids who all exercise, and seeing plenty of women that look like me complete a 10k in central London a couple of weeks ago, I decided the time had come. I have completed week 2 and am really enjoying the experience (not so much the running itself - which is hard - but the sense of achievement) but on my 5th run I felt some aching and tenderness in my left inner shin which lasted a day. I went to a specialist running shop and bought new shoes in case that was the problem and did run 6 yesterday. Legs were fine when running but the rest of the day both shins were sore. They feel ok this morning, just a bit of residual stiffness. I don't know whether this is an injury/potential injury that I should rest, or just general muscle stiffness from new exercise that it is safe to ignore. I have pretty flat feet if that is relevant. I really don't want to stop running and lose my momentum, particularly as I am already feeling the benefit. Any advice?
