The Penn Relays is an event that has changed with the times, sometimes even leading the way.  It was the first invitational track meet to prosper that welcomed all races and all schools from the outset and without interruption. The Penn Relays was the first invitational track meet with separate divisions for colleges, preps and high schools to show any degree of success and continuity.  Within five years of its start the Relays had added junior high school events as well as individual events, which included several of the great post-collegiate stars of the sport.
