14 Products Every Marathoner Should Own, According to Pro Runner Emily Sisson

UCAN Energy and Protein Powder ($55)

Fueling after a long run is key to replenishing your energy stores and getting the recovery process started. But eating right away can be easier said than done, especially for those with sensitive stomachs, like Sisson. Her go-to is mixing this UCAN powder, which is formulated with the recommended amount of carbohydrates and protein for post-exercise, with some almond milk. (She uses the chocolate-flavored powder, and says it tastes like chocolate milk.) "It goes down easy," she says. "I struggle with protein drinks, they really upset my stomach. But my stomach digests this really well." She'll often pair this drink with an energy bar right after her run, and then have a proper lunch a while later.
