Georgia Institute of Technology
Georgia Tech students hold a heated, long and ongoing rivalry with the University of Georgia, known as Clean, Old-Fashioned Hate. The first known hostilities between the two institutions trace back to 1891. The University of Georgia's literary magazine proclaimed UGA's colors to be "old gold, black, and crimson". Dr. Charles H. Herty, then President of the University of Georgia, felt that old gold was too similar to yellow and that it "symbolized cowardice". After the 1893 football game against Tech, Herty removed old gold as an official color. Tech would first use old gold for their uniforms, as a proverbial slap in the face to UGA, in their first unofficial football game against Auburn in 1891. Georgia Tech's school colors would henceforth be old gold and white.

Thanksgiving Day high school football rivalries date back to the 19th century, and the Harvard-Yale rivalry ("The Game") is the oldest rivalry in college football. The Boston Marathon is run on Patriots' Day every year; it is a New England cultural institution and the oldest annual marathon in the world. The race offers far less prize money than many other marathons, but its difficulty and long history make it one of the world's most prestigious marathons.
