Callum Neff ran the Katy Half Marathon in Texas on Saturday 13 February 2016 and pushed his 20lb (1 stone 6lb) daughter Holland in a 22lb (1 stone 8lb) running pram for 13.1 miles.
He was attempting to beat the one hour 13 minutes 2013 world record for the fastest half marathon with a pram and completely nailed it.
Neff completed the race in one hour 11 minutes and 27 seconds.
The average finishing time for the half marathon (without a pram) in America, according to the Running USA's Annual Half Marathon Report, is two hours two minutes for males and two hours 21 minutes for females, which makes Neff's time even more incredible.
"It was just a truly epic day to share with my youngest daughter," Neff told Today Parents.
"It shows that anything is really possible and that being a dad and working doesn’t mean you have to give up on other dreams and hobbies."
Neff uploaded photos of the race on Instagram showing him passing the finish line.
