308 Not quite 10 pounds

So I ran another 5k distance today.  I felt very tired afterwords but the good news is that I weighed myself afterwords and I came in at 308 pounds.  It's not quite the 10 pounds that I was predicting last week but I'm not upset.  In the past when I got into running I was loosing about 1 pound a week so a 7 pound loss is actually pretty good.  I'm guessing I will loose another 5 pounds by next friday and I will be under 300 pounds in about 3 weeks.
