Some men run faster after becoming fathers. While research is lacking, runners and scientists have theories about why. The article “Is ‘Dad Strength’ Real?” from Outside Online explores why some male runners hit peak performance after becoming fathers, suggesting that the responsibilities of parenthood might bring renewed focus, motivation, and structure to training routines. Drawing on insights from sports scientists and elite athletes, the piece investigates whether this so-called “dad strength” is more than a cultural myth. Research from our team – led by Dr. Francine Darroch and Sydney Smith – contributed to this conversation, offering evidence on how shifting identities and life transitions, such as fatherhood, can influence athletic performance and well-being.
