Stephen Biebelhausen ran a 4:17 mile while pushing his child in a stroller at the Guardian Mile in Cleveland on Saturday, a time about nine seconds under the recognized world record for the event. CITIUS MAG, which called the race and first surfaced the result, reported the time; official results from the road mile had not been posted by Sunday.
The current Guinness record for the fastest mile pushing a stroller by a man is 4:26.29, set by Silas Frantz in Arroyo Grande, California, in June 2025. Biebelhausen’s time, if certified, would lower it by a wide margin for a record barely a year old.
Biebelhausen is a former college distance runner. According to his Miami University athletics bio, the Rochester, Michigan, native ran for the RedHawks and posted a 1500m best of 3:48.11, ninth on the school’s all-time list; his career results include a 4:06.68 indoor mile.
A second runner, also pushing a child, finished in 4:32, according to CITIUS MAG.
The stroller mile has become a real record category in recent years. On the women’s side, Kaitlin Donner ran 5:11 in 2024, and runners have chased longer marks too, including a 1:08:04 half marathon behind a stroller.
Guinness marks of this kind are not official until the organization reviews the documentation, and the rules require an approved stroller carrying a child above a minimum weight for the full distance. Until that review is complete, Frantz’s 4:26.29 stands as the record.
