During his time at Stanford, Ayrault served as captain of the Cardinals' rowing team. Stanford's Department of Athletics later inducted Aryault into the school's Hall of Fame. He completed his master's degree at Harvard University in Cambridge, Massachusetts.
Following his rowing career, Ayrault taught at Lakeside School in Seattle, Washington. After Lakeside School name him as their headmaster in 1969, he served in that role until 1990. In 1971, Ayrault guided the merger of Lakeside School (then an all-boys school) with the all-girls St. Nicholas School. During his 21-year tenure with Lakeside School, Ayrault oversaw funding campaigns to construct Pigot Memorial Library, a field house, and St. Nicholas Hall for Humanities and Arts. Students who attended Lakeside during that period included Bill Gates and Paul Allen, the co-founders of Microsoft Corporation.
