As a keen hiker and backpacker, the best way to train to carry that kind of weight on your back is to .... carry that kind of weight.
Although you may want to first start out with something lighter - say around 10 lbs, and then build up from there. Moving at high speed with a heavy pack can be very hard on your shoulders as the straps jerk up and down on your shoulders - at least until you learn a smoother, more even stride.
The other thing is that a book bag may well be able to handle 25 lbs, but carrying 45 lbs is probably into the range where you need a framed backpack to help transfer the weight to your hips, rather than having it all hanging off your shoulders.
I'd also strongly recommend including planks in your strength training routine. This move is really good for your back strength, which is necessary to support a pack and keep yourself balanced and stabilized.
btw, those speeds seem quite fast for civilians carrying that kind of load. Are you sure you have the figures right (eg. were the distances in kilometers rather than miles?)

Hey, I would also suggest making sure you work really really hard to strengthen your core, back and shoulders. If you carry a heavy backpack a lot, it can slowly stretch and potentially damage important nerves in you shoulder/neck (brachial plexus). Once in a while for work isn't unreasonable, but if you're planning on training with it, make sure you build up your strength in all the muscles supporting it. -I am a PA student and we talked extensively about damaging your brachial plexus in Anatomy! I just don't want you to get hurt! Good luck!
I think in most instances in the employment you describe you would be carrying things in a backpack or similar arrangement. Considering specific adaptation to imposed demand as a training mantra I suggest you adopt carrying whatever load it is in some form of backpack.

This may be a bit strange but I'll ask anyway. I'm in the process of applying for jobs as a wildlife biologist and wildlife biologist technician (trying to keep an open mind). In some of the job descriptions it mentions the ability to carry x amount of weight. For example, in one position I was looking at it state that the individual should "be able to carry 25 lbs for 2 miles in 30 minutes or 45 lbs for 3 miles in 45 minutes."**
I can do the 2 miles in 30 minutes and the 3 miles in 45 minutes. I'd like to add my book bag that would equal 25 to 45 lbs. Do you guys have any suggestions? I am aware that things will be different (the things that I'd be carrying) once I'm in the field (no matter what position I obtain).
I am also doing strength training 2 to 3x/week.
**I apologize for not having the link to reference but I'm going through several websites looking for potential jobs.
