I have just enough 10/3 to run a circuit in my garage if I run the cable
under an aluminum threashold. It fits under there like it was designed for
the purpose, but that doesn't mean it is okay... The cable will go through
studs on a wall, down under the threashold, and continue through the wall on
the other side.
Obviously I will have to be careful to avoid snagging the jacket on any
edges, but other than that is there any inherent reason not to do it?
The alternative is to go over the door, and I would have to buy a roll of
cable to do that. Since I don't anticipate ever using 10/3 again, I would
really like to use up what I have rather than buying even more.

It's a very unusual place to run a wire, and that means that no one
would hesitate to take a Sawzall or crowbar to the door and threshold
to remove it. Someone might try to throw in a couple extra screws to
hold the threshold down if it loosens over the years.

As someone who performs selective house surgery during remodeling for
others, I have encountered far too many "it seemed like a good idea at
the time" solutions. Your threshold-as-conduit solution is one of
them. Could it work? Sure. Is it a good idea? No.

I realize you're trying to utilize the cable remnant, but saving money
doesn't factor into the safety issue. The difference in price doesn't
justify the lazy man's solution. BTW, you could always sell the 10/3
you have on Craiglist and buy what you need.
