So I think I remember feeling like this last time in week 2... the bottom half of my legs hurt so much!! calves, outside of my legs... (no idea what that muscle is called!) I have problems with my feet so wear insoles in my trainers and might need to get some new ones fitted. But yeah my goodness so much pain... but I got through it.
Does anyone else find that it's not so much breath that is the challenge but lower leg pain?
