Was that "runner's high"?

I've been running basically every other day, this is my 4th run, and I wanted to make it count. So I set out on an easy route that we usually drive, it's longer than I have done but it's a straight shot. No turns.

Getting up there got to be a little hard, I got winded a couple of times and the bottom of my feet were hurting again from the unaccustomed style of running-barefoot, which causes you to slap your feet a little more when you run. However, it keeps you from using your heels as a landing pad for all of your body weight multiplied by the force you're landing with.

As I was getting to the half way mark of my run, the sun set and I came to a rather dark section of sidewalk. I felt a car pull next to me. It was a cop! He was scouting me!! Apparently, a man with a Camelbak and barefoot running shoes looks suspicious, which is refreshing since I actually thought I could only look ridiculous. "Yes, Mr. Officer. I did go buy these funky shoes so I could pull the perfect burglary and stuff my little camelbak backpack with the loot." Really? I looked like death constipated. I was obviously struggling just to keep moving. If this doesn't say "a poor fool torturing himself trying to exercise" then I don't know what does.

I know that watching a rather stocky brown man running isn't the perfect stereotype of a runner, but I think scouting me was a bit too much. Brown people run too! Maybe I should take him with me to the border. We run too; and we're dang good at it. Whatever, I just kept running. He pulled ahead and then pulled over. All I could think was: "Great! I don't have a way to identify myself because I left my wallet at home" Who brings that kind of stuff with them when they run? "Well, at least I'm not in Arizona. The guy made a U turn and left before I got to him. That was close. However, that's not the story I was going to tell you.

On the way back, after I reached my desired distance, something interesting happened. I started running in such a way that felt rather effortless. I am no totally sure how to explain it. It was almost like my posture was doing a lot of the work and I was leaning just enough to move me forward. Then, my feet were catching me and keeping me from falling on my face, basically just keeping me up. It was even a faster pace than I had had in the first half of the run. I wasn't getting winded, in fact I felt better than on the previous last couple of blocks. I was not leaning forward like a tired runner, I was almost perfectly straight with my chin up. It felt like I could go on like that forever, it really did, but my weak legs started to give up on me and hurt a little. So I walked for a bit. What a feeling though!

Have you ever had runner's high? If so, what does it feel like? I know I've never been even close to it. When I was in High School, I wrestled and we did tons, just tons, of running. However, it was never long distances, or long times but that's when my best running too place, that was when I was in my best shape ever. My fastest 1 mile was 6:30. Yeah, like you're going to get runner's high in under 7 minutes! 

Update: no, that wasn't runners high. It was a slight descent of terrain on my way back. LOL
