Saw this over at the other place. Might be of interest to anyone currently serving in the RNR but looking for something a bit more challenging: It's worth pointing out that you'll need to be within commutable distance of London for this to work. Of course it goes without saying that your phyz will have to be absolutely top notch. Currently the hills phase of selection involves 96km over a weekend while carrying a hell of a lot of weight. The pass speed required to bang this out successfully is actually quicker than that required for SF(R). No fatties.
