What Are We Looking For In A Hydration Belt?

While researching and reviewing hydration belts for marathons, we rated them on the following categories:

Water Bottle Holder

  • It is important to have room to hold other accessories, but the main purpose of the belt is to carry at least one water bottle. After all, we are reviewing hydration belts, and the purpose they serve is to keep you hydrated during long runs.
  • Hydration belts are sized for various different water bottle quantities and capacities. Be sure to select the right belt depending on how much water you drink while running.

Adjustable Waist Strap

  • Unlike a t-shirt, hydration belts should be designed so that one size fits most (OSFM). An adjustable waist strap makes that possible. Despite covering a wide range of sizes, the hydration belt should still sit secure on your body.

Additional Storage

  • Typically when you’re going on long runs, you’re not just bringing water to stay hydrated. Although hydration is the main purpose of these belts, many are designed with additional storage for other accessories. The hydration belt should have additional pockets big enough to bring items such as your smartphone, keys, credit card, energy gel packs, and protein bars.

Light Weight

  • The hydration belt should be lightweight, and designed from breathable material. You’ll be wearing it while running long distances, the last thing you want is a heavy belt slowing you down.

Balanced and Secure

  • Hydration belts should be designed to sit balanced and tightly secured around your waist, as almost an extension to your body. The last thing you want while running is a hydration pack that bounces.

Considering all that was discussed above, our top 5 picks reviewed in this article include (1) G-RUN Hydration Running Belt, (2) URPOWER Running Belt (3) Nathan Peak Hydration Waist Pack (4) PYFK Running Belt, and (5) AiRunTech Running Belt.
