The miler led the Cyclones to seven conference team titles and ran on 19 conference-winning relay teams. Conger added a conference championship at 880 yards in 1926.

Conger compiled a two-year unbeaten streak in the mile from 1929-30. He won three National AAU mile championships and three more U.S. crowns at 1,000 yards.
