This victory broke a streak of wins by international athletes, making Mantz the first American to win the event since Galen Rupp in 2008.[7]

The 2021 NCAA Division I Cross Country Championships saw Mantz repeat as the winner.[8] He covered the first 5k of the race in 14:16.4 and the second 5k in 14:16.7, finishing in a course record of 28:33.1.[9] The win concluded an undefeated season of cross country for the collegiate.
