And then there is the issue of the time difference for the sound of
the report of the starting gun to arrive at each of the starting
locations of the ears of the various runners. When the runners are
initially spread out all over the track this could be a significant
difference when the speed of sound is only some 340 m/s (0.01 s for
every 11 ft of difference in distance in the runners' starting
positions to the starting gun).

No longer a problem. There is a speaker located at the back of each
starting position. The 'gun' is a switch that starts the timer and sends
the signal to each speaker. Every racer now has the same advantage.
