We've sorted through old results best we could to get an accurate all-time list for every classification. These are results that are in the MileSplit database only, so we have less and less historic results and nothing really prior to 1997 as grade years aren't indicated in results we have. Some years we only have state meet results that are reflected in our rankings. We'll put out all-time list by grade for each grade and boys and girls over the next few days. If you have older results that would influence these list you can shoot us an email at jcreasy@MileSplit.com. Eventually I hope to add in what course these performances were run on as we update the list as the years go on. Also schools reflect schools at the time, not school they graduated from.
