Please do not leap in with both feet. I know its only ACF, but my question is a serious one. I was keen to introduce the bleep test at my det, but was told we would need a PTI to do so. I find it difficult to understand as according to the APC syllabus we can run cadets around on speed runs no problem. My OC assures me that the course would kill me. I'm 51 but I take regular exercise running every day. Does anyone have any experience of the PTI course in an ACF context? Oh and why the bleep test? I think it is easier to measure progress than running around chairs in the det car park.
