I have been running outside since the beginning of January and even now, every time I start my run/jog, it seems to feel like very hard work. The first kilometre feels like I am running in slow motion, my breathing is all over the place, my legs feel clunky, and I'm thinking, "oh man, I don't think I can run very far today." It is probably just after 2k where I feel a bit of an improvement and things fall into place. This happens every time. Does anyone else experience this?
