Ken Posner is an ultrarunner, barefoot hiker, and challenge-seeker whose latest book, Chasing the Grid, chronicles his quest to summit 35 Catskill high peaks in every month—a challenge known as “The Grid.” That’s 420 climbs, through every season, in pursuit of something deeper than endurance.

In this episode, Ken shares how the experience became a spiritual journey, shaped by minimalism, transcendentalist thinking, and a deep connection to the land.
