Host Celeste Fong talks with Greg Smith about his running journey from college runs and marathons to technical mountain ultras. They cover standout races—from Spain’s rugged Pyrenees course to Mid-State Massive and Old Dominion—plus the thrill and challenge of trail versus road running.

The conversation also explores balancing training with new fatherhood, sleep deprivation, race planning and fueling, community support on the trail, and facing risks like allergies and the surreal moments that come with ultra-distance running.
