What about a data link via a laser-beam? I realize that the distance
you're covering is enough that you will have to calculate for the
curvature of the earth, but if you had towers at either end you
should be able to aim a beam at a target and get the signal from the
timer at one end to the timing booth at the other end without having
to deal with wires. I don't know much about how the timing system
works now, but if you had something at either end with a beam that is
broken to signal the start/end of the course, those devices could
have a synchronized clock, and even if the signal is broken, the time
would be measured and stored for re-tmit when the link is
reconnected. Just a thought.
