There is no way to make it into a sketchup file, but you can turn the entire track into a .3ds file, and upload that into sketchup using the construction kit. Mind you though it's a HUGE file, and I don't think that too many computers can take that enormous file and upload it into sketchup, so you would most likely want to break up the track into smaller segments.
So, my friend came up to me the other day and asked if I wanted a frozen banana, and I said no, but I want a normal banana later, so... yea.
