Tailwind Nutrition Endurance Fuel, Grape, 50-Serving Bag

It works above and beyond, it will keep you going forever. I race dirt bikes in the desert and this stuff will keep the cramps away 2+ hours into a race when other things like Liquid IV, Powerade, Gatorade, and such brands have failed. This is performance fuel, not a gimmick drink. The flavor could use work, it's like funky water with a hint of something, but I'm not drinking it for flavor so I ain't taking points off.

I use this during long rides on the bike trainer in Zwift. It seems to do a good job at keeping me hydrated and restoring the electrolytes I sweat out over 2-3 hours. It also provides enough easily digestible calories that help keep me going and not fading. I also seem much less prone to being completely flattened once I am off the bike. To those who left reviews complaining about the sugar content… that’s kind of the point! This is marketed as “Endurance FUEL” - not as some artificially sweetened zero calorie sport drink. I don’t use this for shorter rides when I just want hydration. Only when I expect to be exercising continuously for multiple hours and burning 1000+ calories. Other considerations - it mixes easily, taste is decent (just about perfect when mixing 2 scoops of mix into 20 fluid ounces of water), and there are no annoying dyes that stain your water bottles if they are plastic (or other things if spilled). I do wish that the provided scoop was a bit narrower to help avoid spilling the powder when trying to mix it in a sports bottle without a funnel. But I really don’t have any other complaints.

Great taste

I use this during marathon training long runs, and it’s the first carb source that hasn’t wrecked my stomach. Optimal fueling during racing needs something like 50g to 60g of carbs per hour which is hard to get through gels alone. At the end of the race, I can’t stomach another gel! This is a great solution instead of or in addition to. I find it to be very effective at helping me avoid the dreaded wall by getting in enough carbs. I get the bag instead of the single-serving packets, and I find it to be the better way to buy it if you’re using this regularly. You scoop out exactly what you need per bottle instead of being locked into someone else’s serving size. One thing worth flagging for other readers: I haven’t measured out the exact carb count per scoop against what’s on the label, so if precise fueling numbers matter for your training, check the label yourself rather than going off my scoop-by-feel approach. This is my preferred flavor!

Trying this for longer runs. I like the flavor. Had a run today and it seemed to help keep my energy level up. Hoping it continues to perform.

I really enjoy the flavor of this electrolyte powder and the product hydrates well.

My son takes it before early morning trainings as meal replacement. It keeps him energized during the training.

Seems to work well so far.
