I ran 3 miles under 18 minutes. I ran 1.5 miles to the beach which took my 8 minutes and then the run back took me 10 minutes.
Sounds good mate! Try doing the first run to the beach at a steady pace and then the run back as fast as you can, because that mimics the BFT
You're still pretty young though, so don't over exert yourself otherwise you can risk injury a lot more than someone who had a bit more experience training or is simply just a bit older, naturally your body will toughen up and get stronger as you age.
While you can join at 16, most people recommend you give it a couple of years at least for your body to develop. I'm 19 at the end of the month and I'm not going to continue my application until April next year(for medical reasons).. I could be 20 years old by the time I've earned my green lid, and I'm definitely glad it's that way.
Of course it's down to you, just weigh up the pros and cons of applying now before you actually commit yourself. There are many people on this forum who have extensive knowledge of the Royal Marines (Careers advisers, ex-Royal Marines and Serving Royal Marines are on this forum) which can help you out, but they can't make the decision for you. Sorry for the long post
