I needed a part time job to get me throught the summer so joined the TA as a alternative to working in some shity call center or the like

How ever the guy at the center told me that my selection is in about 4 weeks time and they give you an idea of what the army scene is all about but also test your fitness and there is a 1.5 mile run witch must be ran in under 13 mins or you have to wait another 3 months to try again

Sounds easy for some but i can run the lenght of myself, ran around the local loch today and its 1.1 miles round and did it in 9:13 but i was totaly cunted, weezing like fuck and i couldnt go on any more

The guy at the TA center say running once only is a waste of time and i should be running for about 40 mins, so thought i would ask on here as i know alot of you do cardio

So does anyone have any training tips for building stamina?
