how to run low voltage wires for under cabinet lighting

i want to set up low voltage xenon "puck" lighting under my kitchen cabinets. The power source is an outlet inside an upper cabinet to the far left. i will space about 6 pucks over an eleven foot span as i go to the right. I want one continuous string of circuit. My question is what protection "sheathing" do i need for the low voltage wire run? Some parts of the wire will be tacked up under the trim (i.e it outside/under the cabinet), while in other spots it will run INSIDE the cabinets as i go over my range to the far right cabinets.

the dumb/dumb way is just for me to staple the wire tucked up out of the way.. but effectively if you open some cabinets you will see the low voltage wire crossing through the cabinet. is there some sort of "sheathing" that code requires for "exposed" low-voltage wires?

I use a plastic raceway that is available at Home Depot. It has 2 sided tape to stick it to a flat surface, and has a hinged cover.
It is sawn to what ever length is required.

No covering required for low voltage wiring.

An alternative to the Home Depot raceway mentioned above is split plastic tubing. WalMart et al sell it in the Automotive Dept. It's black, about 1/2" in diameter, flexible, and will hide 3 or 4 loose #16 wires.

Not sure your exact configuration but I wouldn't bother with sheathing. It just makes the wire more visible and objectionable. I would run as much wire under the cabinets tacked behind the cabinet faces so its not visible. I would then drill and run inside cabinet, again behind cabinet face in a front corner, to top of cabinet, drill another hole through top of cabinet and then behind the cornice or crown molding across to range and then back down.
