After a long or hard ride, it is important to replenish what you've lost as soon as possible. Since food takes time to cook and many of us don't feel like eating right away, a recovery drink is a good option to get the carbohydrates and protein your body needs. Find one that has a 4:1 carbohydrate-to-protein ratio, which is good for rebuilding muscle. There are lots of different products on the market, so be sure to check the quality of the ingredients.
