How do I use Endurance Fuel?

For endurance workouts, we recommend starting with 2-3 scoops (or one packet) with 18-24oz of water. Adjust your serving size as needed based on hunger and training effort.

What is the recommended serving size?

Start with 2 scoops (or one packet) in 18-24oz of water and adjust based on calorie and carbohydrate needs.

Can I use Endurance Fuel with gels or other foods?

Endurance Fuel is designed to be your only fuel source but we get it if you want to mix it up. When taking in other foods along with Tailwind, make sure to account for the additional calories to keep your gut happy. That might mean reducing the amount of Endurance Fuel you take in per hour.

How much caffeine is in the caffeinated flavors?

Caffeinated Endurance Fuel contains 35 mg of caffeine per scoop or 70mg per single serving packet.

Can I mix Endurance Fuel with other products to add more electrolytes?

Endurance Fuel is meant to be used as a standalone product as each scoop contains 310mg (620mg per packet) of sodium which should be enough, even for salty sweaters. We recommend increasing your liquid intake on hot days instead of adding a product such as Rapid Hydration to your Endurance Fuel mixture.

How do I carry Endurance Fuel out on the race course?

Tailwind is easy to mix in a hydration pack and our single serving packets fit nicely in a cycling jersey pocket. You can also make a concentrate by mixing Endurance Fuel with a small amount of water (enough to make it viscous) and carry it in your water bottle or soft flask. If making a concentrate, be sure to take in plenty of water to help your body process it.

Can I use Endurance Fuel before or after a workout or race?

Endurance Fuel is meant to be used during your workout, training session, race or adventure, when you are actively burning calories. If you’d like to jumpstart your hydration beforehand, we recommend taking in some Rapid Hydration 30-60 beforehand. For after, we recommend Tailwind Recovery Mix to top off glycogen stores and repair your muscles.

What’s the difference between Endurance Fuel and Rapid Hydration?

Endurance Fuel contains calories (100 per scoop / 200 per packet) in the form of carbohydrates to provide energy in addition to electrolytes to keep you hydrated. Rapid Hydration contains far fewer calories (45 / serving) and is ideal when you don’t need the sustained energy from carbohydrates. We recommend using Rapid Hydration for your shorter or less intense workouts, while Endurance Fuel is the go-to for your longer, sustained efforts.

Is Endurance Fuel Vegan?

Yes! All Tailwind nutrition products are vegan.

Is Tailwind Endurance Fuel Gluten Free?

All of our Endurance fuel flavors are free of gluten, nuts and soy.

Naked fuel good break from sweeter fuels
I tried Naked fuel as I wanted something stronger than water on my ride back home. I liked the single serving pack I tried so will order a larger package next order.

Exceptional Product
Firstly, the flavor is amazing!!! I’m so tired of the berry flavors that seem commonplace. This flavor is unique and refreshing. I mean, who doesn’t love watermelon and lime?
I’ve been a bicyclist for 40 years and never had any fueling challenges until now.
Researching led me to Tailwind and with all the positive reviews, I figured I try it.
Well, let me just say it is a game changer, and I have noticed a big difference on how well my legs feel on 50+ mile rides.
I put 6 scoops of Tailwind in my large water bottle and take a drink every hour.
Highly recommend!👍👍👍👍
