Easier on the gut than other products, milder flavor to avoid cloying sweetness, and more usable carbs and sodium numbers. I also love the Mandarin and Tropical flavors! I stash a few single serving packs in my drop bags as treats!

We are all about hydrating with carbs and sodium on the run and tailwind delivers on both fronts with 25g of carbs per serving and 310mg of sodium!

If you're running an ultra it's likely they will be serving Tailwind (for good reason)... so, definitely wise to utilize through training as well. The Dauwatermelon is my go-to and I've yet to find any palate fatigue using that. Tastes like jolly ranchers and keeps you fueled to push your limits.

This has been one of my favorite fueling products for long runs, ultras, and big training days. What I love most is the simplicity—carbohydrates, electrolytes, and calories all in one bottle. It takes a lot of the guesswork out of fueling and helps me stay consistent when eating real food or gels starts to feel like work. I've used Tailwind during long training runs, races, and overnight adventures, and it has always been easy on my stomach. The flavors are light enough that I don't get flavor fatigue, even after hours of drinking it. When you're deep into an ultra and your brain is no longer making good decisions, having a bottle that delivers calories and hydration at the same time is a huge advantage. If I could only carry one fueling product for a long day on the trails, Tailwind would be near the top of the list. It's simple, reliable, stomach-friendly, and has earned its place in my race kit over and over again.
