A running belt is a lightweight accessory designed for runners to carry essential items while exercising. It typically features a stretchy, adjustable band that fits comfortably around the waist. Many running belts have pockets to hold items like keys, phones, or energy gels, allowing runners to keep their hands free and maintain a smooth running motion. These belts are often made from moisture-wicking materials to prevent chafing and keep items secure during movement. Some models even include reflective strips for added visibility during early morning or evening runs. Overall, a running belt enhances convenience and comfort for those who enjoy outdoor activities.
