Parents these days can sometimes be a little too involved with their children (you’ve probably met one on the sidelines at your kids’ games), but if there’s a time or a place to be fully invested in your little ones, it’s at Parents’ Day. And if there’s a parent to model your participation after, it’s Princess Diana.

Back in 1991, the Princess of Wales attended Sports Day (it’s a thing in Britain, much like Field Day is in the US) at Wetherby School, where Prince Harry was a student at the time. And Lady Di didn’t just show up; she went all in for the mother’s race, even taking her shoes off to compete (while wearing a skirt and blazer, no less) in the big event.

Diana appeared intensely focused, pumping her arms and clenching her fists as she raced toward the string finish line. Sure, she was just one of a handful of involved moms competing for elementary school bragging rights, but you can’t deny that she appeared 10 times more invested than anyone else.
