8. Fuelbelt Revenge R20
Staying hydrated during marathon training is no problem when you strap on the Fuelbelt Revenge R20, which carries two seven-ounce BPA-free water bottles in its back holsters. A Velcro closure lets you adjust the breathable padded waistband so that it doesn’t bounce as you pound the pavement. Stash post-workout beer money and house keys in the tiny removable side pocket.
