Background and youth sports
Mantz completed his first half marathon at age 12, which motivated him to participate in other races.[3] At age 14, he finished a half marathon in 1:11:24, averaging a pace of 5:26.8 minutes per mile. He attended Sky View High School in Smithfield, Utah, where he was a three-time All-American at the Foot Locker Cross Country Championships.[4] Mantz also represented the United States in the junior race at the 2015 IAAF World Cross Country Championships in Guiyang, China. He placed 29th over the 8 km race, leading Team USA to a sixth place finish.[5]
Mantz committed to Brigham Young University (BYU), among offers from several other institutions, including Princeton and Furman.[6] After high school, Mantz took a two-year hiatus from running to serve as a missionary for the Church of Jesus Christ of Latter-day Saints in Ghana.[7][4] Upon returning in 2017, Mantz redshirted his first year at BYU.[4]
His great grandfather, Paul Mantz, was a noted air racing pilot and flight instructor.[citation needed]

Mantz ran for Brigham Young University (BYU). He won a national title at the 2020 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.

At the 2023 Boston Marathon, Mantz stayed in the lead pack for most of the race. Running with a large group of leaders, including Eliud Kipchoge, Evans Chebet, CJ Albertson, Mantz reached halfway in 1:02:20. By the 20-mile mark, he was 45 seconds off the five leaders (which included Chebet and Benson Kipruto). He nearly blacked out at mile 24, but stayed upright to finish as the third American (11th overall) in 2:10:25.[18] At the 2023 Chicago Marathon, Mantz was the sixth place finisher and top American, lowering his personal best by 29 seconds to 2:07:47.[19] His time met the qualifying standard for the 2024 Paris Olympics.[20]

Although Mantz's personal best was the 56th fastest in the field, he produced an eighth place finish in the marathon at the 2024 Paris Olympics.[22] In the lead up to the Olympics, Mantz suffered a two inch tear in one of his quad muscles. 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 the 2024 New York City Marathon.[23] His time of 2:09:00 was the fastest for an American man since Alberto Salazar in 1981.[24]

He set another personal best at the New York City Half-Marathon on March 16, running 59:15; however, the course was not eligible for an American record. He finished second behind Abel Kipchumba of Kenya.[27] At the 2025 Boston Marathon Mantz stayed with the lead pack until John Korir broke off in the final 10k, leaving Mantz with Tanzanian Simbu and Kenyan Kotut to battle for the final two podium places. Simbu and Kotut had a photo finish for 2nd and 3rd and Mantz finished 4 seconds behind them in 4th place and a personal best of 2:05:08.[28]
