OK, I tried cleaning things up.
Here is a treadmill simulation sheet, formatted to be readable when taped to the rafters in the dim man-cave.

The thing this can't prepare you for, of course, is some of the big step-ups and other terrain. I suggest you have your kids randomly toss cardboard boxes or pumpkins or firewood onto the front of the treadmill as you run, say from Barr Camp up.)
Here is the personalized wristband-creator, which should be working. You should not need to sign in to access this. If you are using Chrome or another browser, you may need to hit an "edit in excel online" button at the top in order to start entering your own numbers.
http://1drv.ms/1MsmS3XI think anyone can download these documents as well, though the excel sheet is protected where it matters so the math stays untouched.
Have fun, and I'll see you all soon.
