Test is completed wearing overalls, within 4 minutes and consists of:
a) Entering the water at the deep end
b) Treading water for 2 minutes
c) Swimming for 55 metres without touching the sides or the bottom of the pool
d) Climbing out of the pool unassisted (pool side height is approximately 18 inches)
I'm sure someone currently at/recently left BRNC will be able to expand on timetabled phys and other sports etc.
When I was at Raleigh 18 months ago we did the bleep test for one of our phys sessions, it wasn't a pass/fail, although the results were recorded. Maybe they don't do it any more?
When you're in phase 2 you'll probably be tested on both (based on my experience at Collingwood), after that you'll normally get a choice between doing the run and the bleep test, whether on ship or at a shore establishment. My ship used to regularly provide transport to a nearby running track (HMS Temeraire when we were in Pompey) for those who wished to do the run, I presume they all do similar. Otherwise you did the bleep test in the hangar.
Can't answer the original questions about BRNC I'm afraid!
