Former BYU standout Conner Mantz will return to marathon competition on Sunday, marking his first race at the distance in a year. The announcement comes as Mantz prepares under the guidance of longtime coach Ed Eyestone, who was photographed instructing the runner at BYU's track in Provo on April 10, 2025.
Mantz, a two-time NCAA cross country champion, has been building toward this comeback after a period away from the marathon. Eyestone, a two-time Olympian and BYU's director of track and field, continues to oversee Mantz's training as he targets a strong performance in his return to the 26.2-mile event.
