At Mile 0 it's a trail. Then it's a sidewalk, then a parking lot, then a trail, then a quiet surface street, then a trail, then a busier surface street with a bike lane, then a parking lot, then a trail. Or something like that. And that's just the first five miles. You'll find a variety of surfaces and conditions all along the trail.
If you look at the maps, and use Google Satellite and Street View, you get a good feel for what's going on.
