1996 is correct. The only time you'll be contacted to "Retake" the CFA by the academy, is usually if the rest of your application is what the academy is looking for, and they want you, and the CFA is the only area that you messed up. Then, they "may" ask you to retake it.
As for not hearing anything, you usually won't. Whether you passed or failed, you usually don't hear either way. Again, unless they want you to retake it. You don't automatically get to retake it if you fail.
Like everything else, the academy looks at everything. If you truly kicked butt on ALL of the CFA except the run, they may determine that you simply had a bad day. Especially if your application shows lot of high school athletics. The Pass - Fail of the CFA is a bit "Ambiguous". There's a lot of "Depends" built into it; and only the academy will decide if you passed or failed. I wouldn't worry about it. If the run is the ONLY thing in your entire application that was sub-par and the academy wants you, they'll either let it go the way it is or they'll ask you to redo it. Either way, don't worry about it.
