The Race-Day Shoes I Wore at the Boston Marathon, Plus 13 Other Items I Packed

Throughout my training, I used this Camelbak hydration vest ($160). Not only did it store 34 ounces of liquid, but it also had ample room for snacks and my phone. It made storage seamless. Unfortunately, vests are banned from the Boston course. I pivoted and used a Nathan Quicksqueeze Lite Handheld ($35) as a water bottle and storage for two gels, and the brand's Marathon Waist Pack ($35) to store my phone and more gels. I appreciated that the pack had side elastic loops and race bib keepers.
