Box2d - Bike Game - Terrain

Question

I'm using Box2d for a Bike Physics Game, Box2d lets you have fixtures that are convex polygons with 8 points or less, would anyone know of an easier way have a complicated concave terrain, other that just making a whole bunch of fixtures? Or is than the only way?

Any ideas, pointers, suggestions... Thanks in advance! (any language is OK)

Hope it helps!
