Say, didn't Bill have an unlimited supply of track? Now if Bryan has an unlimited space to built one, how about Spa-Francorchamps?

It has two cross-over tracks in it to equalize lane length. And it will fit on a 30x50 foot table.....

Since I have a horse in the race, I'll abstain from voting....

PS. Clearly Track design C should win, though...;-)

Here's my quick stab at it.

100.03 and 100.13 feet lane length

[update]
I'll elaborate a little on the design. I put the cross-over in to make the lane length more equal. Due to the many different radii used (after all Bill had limitless supply, right?) a simple cross-over didn't equalize the lanes completely, but 1/10 of 1 percent difference is pretty close....

As Monte hinted at the fact that the back side of the table was not accessible I kept with the general theme of a long straight of about 20 feet in the back. At the end of the long straight a progressively tighter turn brings you to a wide sweep into a hairpin followed by a widening turn into the second straight. A wide-narrow chicane brings you to the start/finish straight. Out of the starting gate you encounter a wide to narrow carousel followed by some tight turns climbing the cross-over. After the cross-over a parabolic turn followed by the left-right combination brings you to the wide (R4, outer-outer curve) turns crossing the width of the table. The inside of the double turn on the far left of the table is again a progressively tighter turn followed by the second carousel. Finally a progressively widening turn gets you up to speed for the long straight in the back.
