Zach Miller (runner)

Zach Miller is a professional American ultramarathon runner. Born in Kenya to missionary parents, Miller was primarily raised in Lancaster County, Pennsylvania. He ran track, cross country, and played soccer in high school. He continued to run at Rochester Institute of Technology while studying electrical engineering. After college Miller worked in the print shop on the Queen Mary 2 cruise ship, and trained for running on a treadmill, the ship's stairwells, and at ports of call. After his win of the JFK 50 Mile in 2013 with the third fastest time in course history, he turned pro while continuing his cruise ship work. In 2015, his win of Ultra-Trail du Mont-Blanc's 105 kilometres (65 mi) Courmayeur-Champex-Chamonix (CCC) was the first American win of that race. After his cruise work Miller was the resident caretaker at Barr Camp near Manitou Springs, Colorado for five years, which provided the opportunity to live and train at altitude on the Barr Trail and nearby Pikes Peak. After Barr Camp, Miller's primary residence became a converted school bus. After a three-year break to recover from Haglund's syndrome, Miller returned to racing in 2023. He became one of only a few American men to podium at the Ultra-Trail du Mont-Blanc 105 mile race, after coming in second to overall winner Jim Walmsley.
