Then why not change the way an indoor track is banked?
I've been saying this for at least 5 years now, and I will say it again: Move the axis of the banking from the inside of lane 1 to the inside of lane 4!
For example, if you have a typical 6-lane track where the highest point of banking is 1 meter off the ground (that would be the outside of lane 6), it is obviously a foregone conclusion that the further out you are from lane 1, the greater your advantage. And since the start of the 200 or 400 in lanes 5 and 6 are closest to the middle of the turn, the runner goes
slightly up, before going way down, then way up and way down again, before crossing the finish. Of course a runner in lane 1 gets no help, even if the turns tilt, because the track does not rise or drop on every turn in lane 1.
Now, suppose we move the axis of a track's banking from the inside of lane 1 to the inside of lane 4. Lane 6 will rise as high as a half-meter from the middle of the turn, before leveling off at the back-straight, and lane 1 will drop a half-meter from the middle of the turn, before rising at the back-straight. A runner in lane 1 will start on a slight downhill, and go down, up, down and up; for lane 6, the runner will start on a an uphill that is barely noticeable, but the downhill run toward the back-straight and the homestretch is not nearly as obvious as it is on a banked track today.
Such a track as this will lessen the advantage to a runner in lane 5 or 6, while a runner in lane 1 or 2 gets the added advantage of a slight downhill start, thereby improving his acceleration at the start to neutralize the advantage of a runner in lane 5 or 6. Runners in lane 3 or 4 will barely notice an uphill or downhill bank, because the axis of that banking will be between those lanes.
Such a track would have to have its straightaways built almost 2 feet off the ground, to allow for the drop in lane 1 on the turns. I'm sure people will have questions about my proposal, but it has the advantage of never having been tried. Or has it?
