65QUICK HIT A TASTE FOR PERFORMANCE First Endurance EFS Pro
Drink mixes have gone hi-tech. Gone are the days when a drink simply needed a sweet taste and “-ade” tacked onto the end of the name. To play in the big leagues takes serious science and one of the names leading the pack is First Endurance. Its latest mix, EFS Pro, was developed specifically for racing at the highest level, but that doesn’t mean we all can’t benefit from it. First Endurance research led to a surprising discovery—most mixes lack anywhere near enough electrolytes for a long day on the rivet. The result is a formula that can deliver up to 1,866 milligrams of total electrolytes, as much as 10 times more than many popular mixes. Those critical electrolytes come in a blend containing calcium, magnesium, chloride, sodium and potassium. EFS Pro is really like three drinks in one, since it can be effectively altered, based on your needs and ride demands. To get the total electrolytes, EFS Pro is mixed at an 11-percent solution—four scoops—and delivers 160 calories. It can also be mixed at 80 or 120 calories, respectively delivering 933 or 1,400 milligrams of electrolytes. The carbohydrate delivering these calories is multi-branched cyclic dextrin that moves quickly from the stomach, delivering relatively high-calorie hydration without dreaded gut-rot. As much as we love the ability to dial-in calories, to get them without risking a knot in our stomach and ensure we have enough electrolytes to replace almost everything our bodies sweat away, the best feature of EFS Pro is the flavor—or really the lack of flavor. Both Cucumber Water and Lemon Water taste like the names sound, not some blue gas-station sports drink. First Endurance research resources read like a doctoral dissertation in sports nutrition and what we’ve covered here is but a fraction of what EFS Pro offers. It has removed Vitamin C as new research shows that that inhibits training adaptation; it has malic acid, which is shown to stimulate oxygen uptake, and a host of other ingredients from L-Alanyl L-Glutamine to free-form amino acids—all designed to help you get the most out of your body based on what’s in your bottle. When the ride gets long, when the temperature spikes and you’re on bottle No. 6 or 7, that’s when you need the calories

and electrolytes, and that’s when your taste buds can’t bear another swig of syrup. EFS Pro is crisp and refreshing, a taste we crave, even when the bottles are cooking at 95 degrees, five hours into a monster ride. $49.95 (25 servings), $2.10 (single-serve pouch); firstendurance.com P
