Enjoyable run

Leg training and an easy run of 3.7 mile.
The HR was low and I did it at the treamill, it was very good an enjoyable. I almost forgot what is running with out pain...it was like that today, everything was on its place pacefully. The way to start is very important I have to focus on that. I think sometimes I skip the part where the middle speed goes, I have to spend there at least a minute. I just change from slow to the run, today I walked fast first, it helped.
I was feeling very good that's why I stoped on that distance, even though I was wanting more. I had been already about 45 minutes on my feet and that was enough. I hope it helps for friday"s run.
I also thought of doing a considerable stretching session since I remembered I didn't do them on sunday after the long run. They work very good on me, maybe skipping them on sunday made things harder yesterday morning.
