I'm having a hard time trying to figure out how to use blender to trace images. What I'm trying to do is build a race track using blender by tracing a background image with beizers.

I've been reading up on this tutorial: http://www.danielsefton.com/2011/06/create-your-own-racetrack-with-blender-2-49/

This is the only tutorial I could find, but it's using an old version of blender that doesn't appear to be very similar to the latest version of blender I'm using (2.65). Also, I am still a noob with Blender and I'm just now getting around to learning how to use it. I'm mainly a programmer with basic art skills so all of this is a bit confusing. The "Tracing the Track" section is where I'm stuck at, and IMO, Blender is a good tool, but it's functionality and menus aren't the least bit "obvious".

The race track I drew up in GIMP is below. If that's relevant, or not I don't know.

I tried Googling, but that didn't really help unless I've been using the wrong keywords. Any ideas? Thanks.

You might simplify your workflow if you use a vector art application to draw the track to begin with (Illustrator, Inkscape etc.). These applications have better tools to draw 2D curves than modelers in general have and it saves you the step of having to trace it. You can then import the curve into Blender to perform extrusion on it.
