If you would like to have a stroke on the side of the road, then yes, by all means, drink up. However, if you would like to live to ride again, try a glass or water or gatorade. Taking something to increase your heart rate while doing a sport that is, in itself, extremely tasking on the heart cannot possibly have a good outcome. Gatorade is just water with some coloring, flavor, electrolytes, and salt. Red Bull is quite a bit more.
