Is standing for 5 hours the equivalent of running?

I am working a three day weekend, so no exercise, but no excuses just rationalization. I've been thinking. Since my legs and the rest of my body are as tired as they are when I exercise vigorously for a couple of hours am I getting any of the benefits?
Well, maybe. Standing burns 230 calories, so I burn 1150 in five hours. Running 5 miles per hour burns 526 calories. So standing for 5 hours is the near equivalent of a two hour run. Is there a flaw to my logic?

I work again today. Monday I will begin to run again!
