Water is crucial to the function of your body. Water-enriched blood carries oxygen and nutrients to your muscles and whisks waste away from them. Water is also expelled as perspiration–the process your body uses to cool itself. When you exercise, it is essential to replenish water and other nutrients at regular intervals to prevent these all-important processes from breaking down.
A basic guideline is to drink about 20 ounces of water for every hour that you ride. Depending on your personal physiology or warm temperatures, you may need to drink more than this. As you ride, remind yourself to keep drinking at regular intervals, even if you don’t feel thirsty. What you drink depends on the length of time you’ll be on the bike. Plain water is generally sufficient for rides of an hour or less, although there are energy drinks on the market that can provide quick energy for shorter rides.
Use one or several water bottles to carry your plain water or energy drinks. A hydration pack, standard equipment for mountain bike riders, allows you to carry more water than a bottle and typically features some pockets to store your keys, phone and snacks. Use a bottle for energy drinks and supplements, but stick with plain water in your hydration pack to keep things as clean as possible. Bottles can be washed in the top rack of a dishwasher, but a baby bottle brush is an excellent tool if you wish to hand wash them.
For longer rides, plan to carry an energy drink. These products help to replenish essential carbohydrates, electrolytes and calories that you use during exercise. There are many types available, including liquid, powder and tablet forms.
In general, sports nutrition beverages are developed for three purposes, and are specially formulated for drinking before, during or after a ride.
