Yippee I just did a 9 minute run with little difficulty after a 3 week layoff from running because of a hemorrhoid.
I think swimming with fins kept building my fitness and also my calf indurance. I will aim for 9 minutes on my next 3 tests then start aiming for 8:30. I will hit the wall somewhere after that.
I flunked the advanced math test for army systems engineer, so I changed my application to officer corp. Its good motivation.
