Becs Gentry’s Must Haves, From Her Favorite Electrolytes to a $33 Running Belt

Every athlete has certain race-day equipment they rely on to perform their best. For Gentry, that is her Becs Gentry x SPIbelt ($33). "I can not run without it," she says. She even collaborated with the brand to make her very own design, covered in flamingos as a symbol of strength. You can adjust the waistband to sit comfortably at your hips while you are on the move and store your smartphone safely in the middle pocket.
