Wind Resistance

I had a mock PT test today, and I was expecting to have improved in all areas. I increased my push-ups and sit-ups, and my waist measurement is down by and inch and a half. However, my run was nearly a minute slower than six months ago. I'm guessing it's because I've been running more for distance here than for speed. Once I get back to Italy, I'll start running intervals to improve my time; but until then, I'm still just gonna work on burning calories.
