His great grandfather,Paul Mantz, was a noted air racing pilot and flight instructor.[citation needed]
Mantz ran forBrigham Young University (BYU). He won a national title at the2020 NCAA Division I Cross Country Championships in Stillwater, Oklahoma.[8][9] He won by over 20 seconds with a final time of 29:26.1. This victory broke a streak of wins by international athletes, making Mantz the first American to win the event sinceGalen Rupp in 2008.[9]
The2021 NCAA Division I Cross Country Championships saw Mantz repeat as the winner.[10] 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.[11] The win concluded an undefeated season of cross country for Mantz.

While recovering from the injury, he swam up to 10,000 yards in one day and worked on the hills he would face in Paris by running uphill and getting driven downhill in repetition. In his first marathon since the Olympic Games, Mantz placed sixth at the2024 New York City Marathon.[23] His time of 2:09:00 was the fastest for an American man sinceAlberto Salazar in 1981.[24]
