Spline question for terrain and paths

Mosk the Scribe

I'd like to make a 'terrain'/ground layer with a big hill and some mounds - and then I 'd like to send a sled down that hill, following precisely to the contour -

Can this be done by making a spline model for the ground, and is there a way to save that outline to use as a path?? (Or do I just need to draw a path by freehand)

(also, if I'd like 3 sleds to follow the path, each one separated by a few feet from the other and maybe with minor differences, is there a way to copy and paste original path?

Thanks
