In this Winter 2026 Mailbag, the Marathon Handbook crew answers listener questions on some of the toughest — and most misunderstood — topics in marathon running.
From runners who missed sub-3 by seconds, to first-time marathoners chasing Boston, to athletes sidelined by injury, this episode dives deep into both the physical and mental side of training.
