Stay energized during a long session

When you’re doing a long training session or race, it’s crucial to maintain adequate energy and hydration levels. FuelWise™ is a smart fueling assistant that helps you find the optimal way to refuel your body during a longer session, so you’ll be able to keep going and perform at your best.

Avoid hitting the wall

Tend to forget fueling mid-session? The smart fueling reminder tells you when it’s time to refuel and helps you maintain adequate energy levels throughout your session.

Know how much to bring

FuelWise gives you an estimation of how many carbs you’ll need to consume during your session, so you’ll know how much fuel you need to bring with you.

Find the optimal way to fuel your body

FuelWise offers you a personalized fueling wireframe that you can adjust according to your individual needs so that it works for your body in the optimal way.

Stay energized with the smart carbs reminder

FuelWise™ automatically calculates how many carbs you need for your session. It monitors your energy expenditure during the session and adjusts the automatic fueling reminders to match your carb consumption so that you’ll feel energized all the way to finish.

Set drink reminders to stay hydrated

You can also set a drink reminder at your chosen intervals, and FuelWise™ makes sure you remember to hydrate regularly.

The science

The ability to digest carbs during physical activity is highly individual. This is why FuelWise links your training background and other physical parameters to the recommended carb intake rate to calculate the frequency of the fueling reminders. It also adjusts the reminders according to the duration and intensity of your session.
