well basically mate you'd be best to look on your local webpage for the next recruitment day or give them a ring.

not sure how big it is over there but our recruitments are massive and spread over a few days here!

You really do need to be fit, a lot fitter than you think! Again its prob. different over here but try and get a spec of the tests on the day.
There will be a medical, physical and mental exam. mental is pretty easy as long as you revise, need to know a fair bit of maths!
Medical is well a medical, cant do much about it cos if you pass the physical then your medical will be fine, and if you fail either you aint fit enuf!

Basically i started building up to a 3mile run and just reduced the time that got me started then i bought a bleep test and did that down the park until i got to level 9 i think it was.

if you can do that you should be alright, altho nothing can prepare you for the hose run absolute killer!!!!!

it could all be different over there i dunno but if you are at that fitness level you will be fine.

best thing is ring your local station tho, they will gladly talk you through it and may even let you go down there and train (altho strictly speaking they arent allowed so dont push it!)

hope that helps! good luck, excellent job
