I would worry about the track bending up and down even in a pipe over a long distance, unless the roof top is 12' long. I have the HQ Studio 12' frame. Did you order a one piece track? Will this be a round trip or one way? You wouldn't want to warp the track. I'm not much help but wanted to make sure you thought about these things. Maybe some of the other ladies on the board have moved a track over a long distance. Good luck.
