The giant stride is a long-since-removed playground apparatus that dates from early 1900s. Simply put, it was a tall pole with ropes/ladders attached to it. Children could grab hold of the handles and run in circles, so fast that their feet would leave the ground. For safety reasons, it was mostly removed from playgrounds by the 1960s, though some remain.
In graduate school I researched the manufacturing and development of the giant stride, and was fortunate to find a few images of giant strides. I’m jumping back into that research. Readers, have you come across any giant strides or remnants of giant strides? If so, would be willing to share those photographs? If so, please let me know. Your help would be very much appreciated. Here’s what one might look like today:
