Here in Italy, Mario Ferrari printed a beautiful (but very expensive) track
that we regularly use for our Gran-PRIS
competitions. It's 200x250 cm wide with borders of 5 cm. You can see a
picture at the following address:

Sorry, but the rules of the competition are in italian only.
We allowed using up to three motors, one light sensor and two touch sensors.
Plain line following was prohibited: the car should "bounce" on the black or
white borders of the track and drive straight otherwise.
The bumpers could be used in order to reveal slow cars and surpass them.
Usually we don't bother about the programming languages adopted. The real
limiting factor in our races is the thickness of the border lines that
allowed a maximum speed of roughly 60 cm/s. If the robot went too fast, it
couldn't react on time and invariably left the track (and scored a 5
seconds penalty).
Here's a 1 Mb DivX movie of a typical race:
