Here is the one course map I could find. Normaly maps are not provided, since you could study it a bit and gain an advantage.

It's for a Test and Tune event, normally the two courses would be linked and make one long one. The two places you see no blue line and a line of orange dots are slaloms. You have to weave in and out of the cones, alternating what side of the car they go down. Since they are optional slaloms there are no lines drawn, you can start on either side. As you can see there are a few small straights. But even though they are there, much of them can be spend setting up for, entering ans exit the turns. Your top speed will be ~60mph +/- depending or the course/car. Some of the bigger courses, 75mph isn't out of the question, smaller courses (Midway Stadium) 45mph tops.
