For infinite sprint, start sprinting, then after a few seconds (before you slow down again) click the right stick to stab. As soon as you are done stabbing and you pull your weapon back out (you will see the crosshair), click sprint again. Then, after a few seconds of sprinting, stab, then sprint, etc. Just continue doing this until you get where you wanna go. The hardest part is getting the timing down, which isn't really hard at all. All you gotta do is click sprint when you see the crosshair re-appear after stabbing. Simple. You should be fine stabbing every 2-3 seconds, no matter what weapon you have or how much you've ran. This also works in WaW multiplayer, but I put it here because I think it's more helpful in Zombies. This was not discovered by me, credit goes to xbl gt: kain pure evil

i haven't played W@W since MW2 came out but i will try next time i play W@W

This also works in MW and MW2. Had to try it to make sure
