Most my life I've just run 2 miles around 5-6 times a month, nothing big. Not too long ago I bumped it up to 3 mile runs. Well, then something happened, I suddenly found myself no longer tired or out of breath when I ran. I could run and at the end of the run, instead of panting and being drenched in sweat I could simply breath through my nose and stopped sweating within minutes of running. So, I've been pushing myself farther and farther and now I'm doing 5-7 mile runs a couple times a week just fine. My questions:
Why am I no longer out of breath? Is it a cardio thing, breathing pattern, muscles just getting to be where they need to be, etc?
Towards the end of the longer runs it starts to tighten up behind my knee a little. What's going on there and how do deal with that when running? It doesn't hurt, just feels weird and I don't feel like having something snap or tear.
The next day, I'm never sore, I'm just stiff/uncomfortable. It's not like when hitting the bench the next day I have sore muscles. It's more like nothing wants to move, expecially my feet in the morning, they're pretty unhappy. Anything to be done about this?
