Don’t get caught on a long run or ride without an easy source of energy on hand. GU’s Roctane drink mix gives you a blend of carbohydrates from non-competing metabolic pathways, a healthy dose of electrolytes, and small amounts of amino acids to help with recovery. The mix comes in five different flavors, some with caffeine and some without, depending on your preference. Our favorite was strawberry-hibiscus, reminiscent of good ol’ fashioned cherry Kool-Aid. $30 for a 12-serving canister.
