Rough Week

I've been hitting the gym and running about 8 times a week (twice a day M,W,F and once on Saturday and Sunday). Unfortunately, that's not enough. My CO singled me out while the class was on a run (never good) and gave me about a 15 minute chewing out about being a slow runner. My entire class witnessed it too. He told me I will be working out harder and had better drop my time by 2 minutes a mile by the end of this class which is 6 weeks away. Impossible? Probably... I'll give it my best shot. But, I've been giving my best the entire time. I work out more than anyone in my entire class. Still not good enough.
