Sparhawk, you really need to let your body recover. The amount of running you are doing is not only unhealthy, it is counter-productive. Recovery time for a muscle group is every bit as important as the exercise itself.
Everybody: If you are interested in getting in shape safely, I highly recommend getting a copy of FM 21-20 (here is a link to the text:
http://155.217.58.58/cgi-bin/atdl.dll/fm/21-20/toc.htm ). It will explain some basic concepts of fitness that are essential to anyone, not just soldiers. It is proven methodology, and it isn't trying to sell anything.
