<human>: Can you provide a brief overview of the text?

So I run on the same trail every other day. I've been jogging for almost a year and all summer whenever I timed myself it looked like I was hanging around a 10 minute mile. That's fine...I'm not training for a race or anything and so I'm good with that. I also was running about 3 miles a day, no big thang. Like i said, I'm not training for anything so was just trying to get my heart rate up. 

Then two days ago I decided to take a different route on the trail (there are a few different ones) and this particular one has mile markers on it. Believing them to start at one end and measure the full length there and back, I thought I was jogging 3 miles. When I saw that it took me 45 minutes I couldn't believe how slow I was going....I mean there were a lot of hills, but DAMN! So today I decide to run the same route, get an improved time. Then, in the last quarter mile see a 1.5mile marker facing me...except I had passed that same marker further up the trail going the other way...DUH! They measure the trail ONE way. So I accidentally went on a 6 mile jog and my new time is approximately an 8 minute mile! I feel like I can say I go running and not just jogging now! So much winning and excitement, I had to share with some people who could appreciate.
<bot>: Thought I was jogging 3 miles very slowly...like....18 minute miles...actually was running 6 miles at 8 minute miles. W00t!
