Some things we just can't control. Heredity is one of them. Other things, like running your butt off... well that is something we can control.
I've had an interesting week. My runs went really well and I worked really hard. I may have pushed running buddy #2 a little too hard because she didn't want to go out again a second time this week. It was cool, because I went out on my own which allowed me to push harder. I burned approximately 3300 calories this week (I log everything in at SparkPeople). I'm sure that's a high estimate, but even if it was high, it's still pretty darn good.
