I posted this question a couple of weeks ago but didn't receive an answer, probably because my post was hidden in another thread.
My question is: How do they measure the exact distance in an hour run? Does an official run alongside each runner for the last few steps and when the final horn goes they jam a marker in the track? Or does the runner have to stop "on a dime" when the horn goes?
