2. Beet Juice
There are many endurance athletes swearing by the benefits of beet juice to increase their endurance. With good reason, too, because beets have been proven to reduce the amount of energy needed to work out. Getting the juice is important because the nutrients are more condensed and provide a quick burst of energy for your run; that is, raw fresh-pressed beet juice straight from a juicer. Consuming it 2 or 3 hours before your run will give you the best results. It doesn’t taste as bad as it sounds, if you are worried about that! You can also combine it with other fresh juice and still get the same effects.
