My Jogging Session Today (Nothing Interesting...)

Whoa~ Juz came back from jogging, and managed to jog 4.8 - 4.9km at one shot! Though timing wasn't very good (around 30 mins), I was quite shocked I could actually accomplish the *feat*. The last time I jogged, which was 2 months ago, I couldn't even handle my 2.4km. Today, I was just jogging at my own pace, and at first I aimed for 2.4. When I reached the point, I thought "Ahh wad the hell.. Let's go for 3..", n so on. These sort of miracle juz scares me sometimes...
