Having a Green Juice before my run.
1/3 green bell pepper
3 leave dinosaur kale
3 stalks celery
1 big slice cabbage
1 scoop of powdered greens (spirulina, barley grass, wheatgrass, etc.) + a squeeze of lemon juice
This is truly a power drink! Loaded with magnesium and other minerals that are good for your muscles and mind :), and alkalizing. Yummm.
