FAQ

How do I mix and use High Carb Fuel?: Mix one packet with 16 to 24 oz of water and sip steadily over one hour. It can also be mixed in a more concentrated form at the lower water range, with additional plain water consumed alongside.

Do I need to train my gut before using High Carb Fuel?: Yes. Tailwind recommends a multi-week ramp-up to train your gut before hitting 90g per hour. Start with one packet over 90 minutes in week one, then gradually increase the concentration over several weeks. Jumping straight to full use without adaptation can cause GI distress.

Can I use High Carb Fuel alongside gels or other products?: No. High Carb Fuel is designed to max out your glucose and fructose absorption pathways on its own. Adding gels or other Tailwind products on top increases the risk of GI distress because the transport pathways are already saturated.

How does High Carb Fuel compare to regular Endurance Fuel?: Endurance Fuel delivers 200 cal and 50g of carbs per serving from dextrose and cane sugar. High Carb Fuel delivers 360 cal and 90g of carbs from a three-source blend. Use Endurance Fuel for training and moderate-intensity efforts. Use High Carb Fuel for your highest-intensity races and hardest days.

Best For

Cyclists doing high-intensity racing, criteriums, or sustained hard efforts where 90g of carbohydrates per hour is warranted. Requires gut training to use effectively — the individual packet is ideal for starting that ramp-up process before committing to a box.
