As we know, however, track designers are particularly devious and will position turns such that they are too close to use sweeping arcs over the full width of the track, but not close enough for the straight-line method to be practical. Now there is a choice to make: You can straighten the line between the two turns, which forces you to use smaller arcs and go slower over a shorter distance, or you can sweep in a larger arc from one side of the track to the other to keep your speed up, but over a longer total distance. At a recent series of track days and schools, we saw both extremes (shown here) and everything in between. In this diagram, rider A takes the shortest line but has to make the tightest turns, and hence has the lowest speed. Rider B tries to carry more speed by sweeping wide, but ends up traveling much farther than rider A.
