Running 50 Kilometers Through Rome To Understand Stoicism

Ryan Holiday ran 50 kilometers through Rome, passing the city's most important Stoic sites, and he did it because it was hard. That was the whole point. Drawing on an idea from Jesse Itzler, Holiday explains that you should pick something genuinely difficult to do every year—something so ambitious that no matter how the rest of the year goes, you look back and remember that as the year you did that thing. The value isn't in succeeding or failing; it's in having wrestled with something beyond your normal limits. "If it isn't, you're not gonna remember it, it's not gonna mean anything," he says. "So you want to pick something that's big, that's ambitious, that scares you a little bit. And this thing scares the shit out of me."

The Inner Citadel

Running past Hadrian's tomb—known as Castel Sant'Angelo, the castle that protected Rome from invasion—Holiday draws the connection to one of Stoicism's most powerful images: the inner citadel. The real fortress, he argues, has to be inside. When we do hard things, when we train, when we push ourselves physically, we are reinforcing that inner reservoir of strength. Thomas Paine called it "the cabinet of fortitude" when he wrote to George Washington. That inner citadel is what protects us from external events and what we draw on when things get genuinely hard.
