A box of 12 Maurten Gel 160 sachets, each holding 40g of carbohydrate (about 160 kcal) in the brand's Hydrogel Technology. The box carries 480g of carbohydrate, built for athletes running high hourly carb targets over marathon, ultra and long-course triathlon distances.

What's in it

• 12 sachets, each 40g carbohydrate
• Hydrogel Technology that carries the carbohydrate through the stomach for absorption, with no need for water to wash it down
• No colours or preservatives; neutral flavour

When to use it

• Marathon and ultra racing where you want 40-80g of carbohydrate per hour from just one or two sachets
• Race simulations and long runs through a training block
• Back-to-back long days, where a box keeps your fuelling consistent

Planning tip

Start with Gel 100 or half a Gel 160 in training and build up. Use Maurten's Fuel Planner to match carbohydrate, fluid and pace to your event.
