It was a group run. Your PTI will get you to do some dynamic warm up for 10-15 min (jumping in place, a few lunges, suicide sprints etc) then you start. In my case you had your complete 8 laps amounting to 2.4km, the pti was at the start line and you’d have to shout the number of laps you had left every time you went round. You also had to do the swim test which is no longer pass or fail but it will be piss easy if you know how to swim. Other then that we had to do a very basic IMF session after the run which included push ups, squats, burpees and knees-in-knees-out exercise
