Athletics tracks are always run anticlockwise. Does this favour particular runners? Races could surely be run either way, so why never clockwise?Peter Hallberg, Stockholm, Sweden(Image: dlritter, stock.xchng)
I believe it is because when the runners are nearest a spectator, that spectator will percieve the runners as moving left to right - the same direction our eyes move when we read.
Maybe there is a correlation between handedness and preference for running either left or right. I know I have a strong tendency to start running counter clockwise for a race in an open field because for some reason it seems more natural. If you are right handed you most likely have a preference for your left foot as well. So, if you run counter clockwise, your left foot would be on the inside of the track and would take more force when turning a bend. I happen to be right handed and so are most people. It seems like this can be easily tested and proven.
I think tracks should be modified to a figure-of-8 shape. In cycling too. It could lead to some interesting clashes as long distance fields start spreading out...
