Find out what the activities you will be required to complete are and practice doing them. You will need to sort out a training programme to suit all of the above so that you do not over train.
Make sure you prepare your feet. There are many suggestions, like rubbing alcohol on them, washing in salty water, and walking barefoot on sand & hard surfaces. When you get to the physical tests, really look after your feet. Learn how to protect them from blisters or you will suffer a lot of grief. One thing to remember is smooth your socks out as you put them on so that there are no wrinkles in your footwear to rub the skin away.
Why use a sledge hammer to crack a nut when a steam roller is even more effective, and, is fun to drive.
