🇺🇸

American professional ultramarathon runner born in Kenya to missionary parents and raised in Lancaster County, Pennsylvania. Miller's unconventional training journey includes working on the Queen Mary 2 cruise ship where he trained on treadmills and stairwells, living as caretaker at Barr Camp on Pikes Peak for five years, and now residing in a converted school bus. After a three-year recovery from Haglund's syndrome, he returned to elite competition in 2023, finishing second at UTMB and becoming one of the few American men to podium at the prestigious 100-mile race.
