Tailwind NutritionEndurance Fuel, Sports Drink Powder Single Serving with Electrolytes, Non-GMO, Free of Soy, Dairy, and Gluten, Vegan-Friendly, Naked Unflavored, Pack of 12

This stuff is magic! After suffering with hydration issues for years ultra running in Hawaii where it's freakin' hot and brutally humid, this stuff has been a game changer. I tried Pedialyte, coconut water, my own salt/sugar mix, Skratch, and other and still had hydration issues. Now, I know that if I put 1.5-2 scoops in one hand held water bottle, and keep fresh water in another in my other hand, I'm good for 2 hours if I drink both bottles. I then supplement occasionally chugging a full bottle of water at an aid station, and eat whatever I feel like. Just ran my second HURT 100 race with this strategy and beat my previous time by almost 2 hours. I never had hydration issues. Never had cramping. Never was wondering if I was getting all the hydration and electrolytes I need. I prefer the unflavored. It actually has a light citrus flavor that never gets old. I've been using it for 4 or 5 years, and even if I experiment with other stuff, I quickly come back. It's the best. LOVE IT!

It's not my first time using Tailwind, this is now my go-to powder for my running and triathlon races. Last month I finished an 11-hour 50-mile trail race in 70-degree warm weather, many other runners seemed to be suffering from dehydration and sugar deprivation, but not me thanks to constantly replenishing my bottle with a powder bag and water at the aid stations every 3.5-5 miles. I alternated this endurance powder with the Tailwind Recovery powder, as the seller had recommended, to get some protein (I like to have protein for ultra trail runs, which tend to be hilly, and for long triathlons). I never had any gut problems, as usual with Tailwind, despite consuming 11 pouches. Also felt energetic and well hydrated, while others (much younger than me, I am over 50) bonked.

Works greatUse it on bike trips

Solved my teenager's gut bombs that kept occurring after soccer games. Like the lack of flavor. Mix one into a big sports Thermos.

My son used this to help condition for a marathon. This is some awesome stuff.

This particular item touts being “unflavored“. It is anything, but. Telltale sign was the scent when I opened the pouch. Once diluted in water, it was very clear that this has a distinct flavor. While it is not as heavy as all the other flavors, it clearly is not unflavored. Very disappointing. I’m left with the choice of having to buy Gatorade water new product that is truly unflavored possessing all the electrolytes. However, in doing so the plastic is contributing to the landfills.

I love the convience of the small premeasured packages. I like to switch up my flavors on long runs and race days, so the mixed pack is terrific. More importantly, Tailwind is a great product! It makes it easy to keep hydrated and fueled, something I struggled with especially toward the end of my long races (50k). My stomach can be finicky, but Tailwind has lived up to it's promise of "no gut bombs".

The unflavored is awesome! No taste fatigue during hours long efforts. Helped me survive races with temps near or above 100.
