Fitness and weight.

Although I am undoubtedly fitter than most of my peers I am carrying around some excess weight and due to a knee injury I have not done much CV work recently.  That coupled with the fact I am mainly working at a desk has contributed to a pretty fast weight gain.  I now weight 19st4lbs (270 lbs).  I would like to get back to the weight I was when I served in the Army: 15st (210).  I have started running around a local lake (Arrow Valley Lake).  The circuit is approx 1.2 miles.  I have ran round four times in the last 10 days.  My first circuit took 15:31.  My most recent one took 14:42 so there has been a definite improvement.  I am going to try and cut down on the time and eventually build up to multiple circuits.  I will keep you posted on how I do.
