When will this get easier?

Running Log:
3.6 miles - 48:45 min.

I have been running for about five months now. I know I have made improvements, but I have to wonder when running 3 miles is going to get easier. Tonight I ran 3.1 miles at a 4.8 mph pace. And it was hard. I wanted to quit, but I didn't. I can't imagine much more sweat pouring out of my pores. But it does.

When is this going to get easier? When am I going to feel like running 3 miles is no big deal? Does that ever happen? It doesn't seem like a possibility for me. It seems like it is always going to be hard.

Don't get me wrong. After taking two days off last week, I was back on track this week. It was a good running week. I just wonder if it will ever feel easy.
