Most memorable race I've seen:
Mile Relay at the 1978 Indoors. Jackson State and Abilene Christian were tied at 75 points going into the final event. They had the top two times in the event, Jackson State had the individual 400m Champion (Dennis Duckworth) and Abilene Christian had the runner up (Bill Cork, also the runner up in the high jump). Jackson State ran Duckworth on the first leg and held the lead until the final leg. The anchor leg runners got tangled and both teams were disqualified. I Imagine it was interesting when the teams shared the podium for the awards ceremony.
