This is not just for endurance activities, though. It can help fuel any training session, from HYROX and functional fitness to cycling or running.

FAQs Plus

Why does the bar contain 30g of carbohydrates?

Our bars are purposefully formulated to deliver 30g of whole food carbohydrate per serving and makes it easy to stack with other products in our fuelling system.

Are these bars suitable for pre-workout use?

Absolutely. The blend of oats, date paste, and rice syrup provides a steady release of energy, making it ideal 45-60 minutes before training or competition.

Do these bars cause bloating or GI distress?

No. The balance of low fibre and low fat helps ensure digestion is smooth and performance focused without unnecessary GI burden. Also the fat content comes mainly from coconut oil which is rich in MCT's. These are metabolised faster than other fat sources and can be utitlised as an energy source.

Are MARCHON™ Fuel bars gluten-free?

Yes. We use gluten-free oats and gluten-free cereal balls to ensure the bar is suitable for those with gluten intolerance or sensitivity.

Are the bars suitable for vegans?

Yes. All ingredients are 100% plant-based.

Are these bars heat and cold stable?

Yes. The texture stays soft in colder environments and non-sticky in warmer conditions, making it ideal for year-round training and racing.

Are MARCHON™ Fuel bars tested for banned substances?

Yes. Like all MARCHON™ products, our bars are batch-tested for banned substances under the Cologne list to ensure athlete safety and compliance.

What makes this different from a regular snack bar?

Most snack bars are built for taste or lifestyle. Ours are specifically formulated with versatility in mind. It can be used around training sessions or as a snack bar any time of the day. The compact size makes them easy to consume anywhere.

Great taste and fuel

I took it during a longer-duration Hyrox training session and felt great throughout. Consistency/texture was good, not too runny like some. The unflavoured tasted really good (for an unflavoured) and would definitely recommend.
