Default Thermostat wiring in cold air return?

I'm upgrading to a two stage furnace and I need to run new wires to my new thermostat . The problem is that the basement ceiling is drywalled. I know that you can't run 110 volt wires through a duct, but it is kosher to run low voltage thermostat wires through a cold air duct?

Any other clever solutions?

Thanks!

Default Yup

I have seen cold and hot water pipes running through a duct...you can do what you want I guess.
Instead of running on the inside of the house, can you run it along the outside under the bottom row of siding? I see phone lines always tucked under that bottom starter strip.
Otherwise do you need some small crown moulding in your basement.

Thanks, I also have learned that there are wireless thermostats now - may be a solution.

The first decision to affect the wiring is whether the thermostats will be ... along the floor also allows a faster response time to incoming cold air
