I knew Army lads who could not pass the BFT or CFT,
but away on Exercise for 3 weeks, they would work 14/16hr days with no trouble whatsoever...
The ability to run 1 and half miles in less than 15mins proves someone is capable of a short sustained period of exercise...
The real test sure is the ability to keep going over a longer period...
Some people are geared to be able to run, others are not...the none runners may well be the ones to keep on going....
Now wheres me Duracell's gone....!!!!
