Innovative and groundbreaking coaching techniques earned Bill Squires admiration throughout the distance running world, first as a coach at Boston State College, and then as the founding coach of the Greater Boston Track Club in 1973. Squires achieved his most noteworthy successes with marathoners Bill Rodgers, Alberto Salazar, Dick Beardsley and Greg Meyer, but it was his ability to individualize workouts that separated him from the rest of the coaching fraternity. He was well known for his "simulators," workouts designed to prepare an athlete for a specific course by building confidence and learning to be aware of the stages of each race. Squires was a record-setting miler at Notre Dame, where he also earned All-America honors in cross country in 1954-55. He also coached the Liberty Athletic Club, the nation's oldest women's running club, and his Boston State teams won more than 40 team titles from 1965-78. In 1979, the GBTC won the AAU national cross country team title, placing five runners in the top 12.
