It varies establishment by establishment. The AstroTurf at SULTAN is 8 and a bit times round, not sure of COLLINGWOOD and has been too long since I last ran at RALEIGH. Basically, do your phys and push yourself and you’ll be fine.
@Dreamz I had my PRNC on the 26th of March - 29th of March so have just finished. The run is on the Tuesday just after 9 you get up at 5:45 get you phys kit packed in your daysack and head to breakfast (don't eat loads as in about an hour and 40mins you do your run) you then go to the drill shed and have a session with the drill instructor depending on who you get we had a real good instructor down to earth really funny and kept abusing everyone so was a real laugh. Then you go to the gym hall where you meet the PTI this is where we had our first telling off as people couldn't keep still and he got mad and we had press ups and everything all part of it though. You then have a small amount of time to run to the changing rooms get changed and fall back in outside. You jog to the parade square as a squad given a brief and warm up then told where the run will go. It starts in one corner and it's around the outer side of the parade square 3 and 3 quarter times and off you go. Once everyone has done you go straight back to the gym hall and do your IMF which is fitness with the PTIs one of the hardest parts due to the fact you have PTIs shouting at you if your doing things wrong etc then after this they tell you if you have passed the run or not if you haven't then you get sent home the following morning. After this you visit the bish for a brief of church's in the navy etc then ship visit then more power points. I hope this helps mate any more questions just ask as I said I have literally finished mine week before last so relatively fresh on it all.
