No disrespect to the 1600 m and 3200m distances, but they doesn't serve any purpose of linking the english and metric systems. I think the US high school system should mimic US college system in preparation for those distances. This means mile and 3k indoors, and perhaps 1500m and 3k outdoors (as a replacement for the 5k). Perhaps an occasional outdoor mile would be appropriate to give those few high school athletes a chance to break the famed 4 minute barrier
