Unless you’ve been sleeping under a rock (or spending your free time scrolling Strava), you’ve probably seen the viral churning-butter-while-running trend. It looks pretty simple — grab a carton of heavy cream, pour it into a Ziploc bag, add some salt, and head out for a run. In theory, by the time you return, you’ll have churned butter, ready to spread on your toast.
I’ve seen this trend all over my Instagram and TikTok for the past few months, so now I’m back training for another marathon. I decided to give it a try. In a heatwave, of course. I have some thoughts.
