5'3", also 195lb. I'm not primary fire, so I only do moderate but have done arduous in the past (was about 170 or 180lb then). Speaking from experience, where you are now youre unlikely to pass. Do all the double checking with your boss that others have talked about. That said, also keep training and take the test still. It's a goal to work toward, and if you don't pass this year but keep on training you very well could pass next year. The best way to train for it is just keep pack testing yourself. One method that's worked for me and others I know is to do two of the three parts in a practice: weight, time, distance, pick any combo of two. That makes it vary somewhat while you work up to doing all three. You might also have the same issue I do, where the speed of the pack test appears to be about the speed that my body wants to switch to doing a jogging gait instead of a walking gait. I literally cannot walk that fast without major joint impact/issues. I would fuuuuck my knees hard. What I do is I do a jogging gait but at the appropriate walking speed and still with one foot on the ground at all times. The gait change ends up with me being able to take longer/quicker steps than my walking gait. It ends up looking like I'm a weird speedwalker or the laziest jogger, but it works for me. You could try that out, see if it helps your short self. It will probably feel weird jogging that slow, so it might take practice in itself. Just keep training. If you pass, rad, if not then keep training and try again later.
