Why Running Belts Actually MatterThink of a running belt as the small, quietly competent accessory that always has everything under control during training season. Unlike the neon fanny packs of yesteryear, today’s belts are made to move with you, not against you. The Hydration QuestionIf you run long, run hot, or both, water becomes non-negotiable. Some belts are built with dedicated bottle or flask spots, keeping the slosh low and centered so you don’t feel like you’re wearing a pendulum around your waist.
