Downhill ski slope

Hello to all,

I'm trying to find a way on recreating the descent of a ski slope, with turns, accelerations, bumps, flatter areas. The graphics will be pretty basic but I do need to give that impression of downhill. Not being a PRO in 3d space on after effects, would any of you guys could give me a heads up on how I could do this. I tried looking for examples or tutorials but unfortunately I haven't had any luck.

Hope someone can help me or send me a link of a tutorial of somesort.

Thank you
