Good point. I think that hurdle spacing and height should almost always be less / lower than competition spacing and height. We don’t expect athletes to be able to run competition speeds in practice so why should we expect them to run with competition hurdle parameters. Hurdle clearance is largely dictated by the velocity of the athlete is approaching the hurdle at, as such it would be foolish to expect them to run competition heights and spacings without having competition speed. In reality, adjusting the heights and spacings should ultimately make the practice MORE like how they would run in a meet rather than less.
