Hello all.. I start basic training at the end of next month and quite excited, i have a very good fitness level and all but i have one problem.. I am a very poor swimmer, ive tried to learn past weeks but find that im a very poor swimmer. Now i know that for basic training i need to swim 100 metres in under 4 minutes. I think i will find this very difficult, do you think i will be backtracked until i can do it? All replies are helpful.. Thanks..
