The burning sensation in my lungs is a good thing...

Yesterday I hit 5k for the first time. 26:45. Not bad for someone who is designed in every way to not be an endurance runner. I'm hoping to get the time down around 24:00 before the rockets hold their yearly fun run. Should not be too hard barring any sort of stress fracture or anything. My lab mates are just going to have to get used to working next to the sweaty guy since i'm forced to squeeze my runs in during extended wait times of experiments.
