"And from what I have heard, its not that much of a beasting, but I guess that varies for each individual."
True, its probably not as physically demanding as JROC or Sandhurst, but its not a complete walk in the park and you do have to have some grit to get through. I found it to be challenging - both mentally and physically. I was very very fit before IOT - I had spent years going to the gym minimum 3 times a week plus a lot of tennis at club level. I would say that after the initial 4 weeks BIM at IOT, my VO2max actually started to decrease. I remember on a certain stretcher excercise being in agony with achilles tendonitis. Without a team encouraging me on, I wouldn't have lasted the course. I learnt a lot from it.
The other side of it is being able to put up with ironing and bulling until 1am, then getting up at 6am for a very long and physcial day.
I felt I developed socially at IOT too. I certainly have respect for the course.
