Cleveland Dad Runs a 4:17 Mile While Pushing His Baby in a Stroller, Chasing a World Record
A Cleveland-area father turned a casual idea into an extraordinary running performance when he completed a mile in 4 minutes and 17.707 seconds while pushing his 1-year-old daughter in a stroller.
Stephen Biebelhausen, a former Division I runner at Miami University in Ohio and an emergency medicine doctor with Cleveland Clinic, entered the stroller division of the Guardian Mile in Cleveland on Aug. 8, 2026. Instead of simply competing for fun, he ended up posting a time fast enough to potentially establish a new world record for a male runner pushing a stroller.
The result was especially surprising to Biebelhausen because he did not believe he was in peak running condition before the race. He said his recent training had not included as many miles as he had hoped, and his typical mile times during preparation were around 4:30 to 4:40 without a stroller.
His decision to enter the stroller race came partly from his competitive background. Rather than entering the elite division and risking a disappointing performance, he thought he might have a better chance of winning if he competed while pushing his daughter, Blake.
That gamble paid off.
Biebelhausen crossed the finish line in 4:17.707, comfortably winning the stroller division. More importantly, the performance was fast enough to put him in contention for the fastest male stroller mile record.
The time would represent a significant improvement over the previous marks associated with the record. However, Biebelhausen’s performance is still being described as unofficial because Guinness World Records has not yet completed its verification process.
Guinness World Records currently lists the fastest mile pushing a pram by a male as 4 minutes and 36.23 seconds, achieved by Benjamin Stern in Mount Shasta, California, on May 2, 2025. Guinness also notes that records can change before every new result is formally published online, making official verification an important part of the process.
Biebelhausen said he had not entered the Guardian Mile with the expectation that he would produce a world-record-level performance. His original goal was much simpler: have fun with his daughter and try to beat the existing stroller course record.
He had also taken Blake out for a faster training run before race day. That gave him a chance to make sure the stroller could be handled safely at higher speeds and that both he and his daughter were comfortable.
The Guardian Mile course presented its own challenge. The race begins with an uphill section and finishes with a downhill stretch, meaning runners have to manage their effort carefully from the start.
Biebelhausen said he did not realise just how quickly he was running until he reached the halfway point and saw a race clock. His split was approximately 2 minutes and 12 seconds.
At that point, he understood that he was running much faster than expected.
Looking at a watch during a race can be difficult under normal circumstances. Doing so while controlling a stroller adds another layer of difficulty. Biebelhausen relied largely on how the pace felt rather than constantly checking his time.
The final result left him stunned.
After crossing the finish line, he had to process what had just happened. He then returned toward the starting area to encourage a friend who was competing in the elite division.
Biebelhausen’s background helps explain why such a fast time was possible. His college running career included strong performances in middle- and distance-running events. Miami University’s records list him among the school’s accomplished distance runners, while World Athletics records personal bests, including a 3:47.62 in the 1,500 metres and a 14:26.19 in the 5,000 metres.
That competitive experience gave him a strong foundation, but running at that pace while pushing a stroller created a very different challenge from a conventional mile.
The stroller adds weight and changes the runner’s mechanics. The athlete must maintain control of the stroller while maintaining speed, positioning and balance. There is also another important consideration that does not exist in an ordinary race: the passenger’s safety.
For Biebelhausen, that passenger was his daughter Blake.
The father-daughter combination quickly became one of the most memorable parts of the story. While the athletic achievement attracted attention, Biebelhausen has emphasised that Blake deserves much of the credit for making the moment special.
He joked that he probably would not have received the same attention without his daughter accompanying him.
The performance has since attracted widespread attention, with coverage spreading beyond the local Cleveland running community. Biebelhausen has also begun communicating with Guinness World Records about the process required to have the performance officially recognised.
That process matters because an exceptionally fast race time does not automatically become a Guinness world record. Record attempts have to meet the organisation’s requirements and undergo verification before a result can be officially recognised.
For now, the most accurate description is that Biebelhausen recorded an unofficial 4:17.707 stroller mile at the Guardian Mile in Cleveland. If Guinness verifies the attempt, the result could become the new official benchmark for the men’s fastest mile pushing a pram.
The story is also a reminder that record-breaking performances do not always begin with months of carefully planned preparation. In Biebelhausen’s case, the opportunity came from a simple decision to combine running with time spent with his young daughter.
He entered expecting a fun race and a chance to challenge a course record. He left with a time that may eventually place his name in the Guinness record books.
For a father who was unsure whether his training was good enough for a serious race, the unexpected 4:17 finish turned an ordinary weekend event into a remarkable family milestone.
