The Precision Fuel & Hydration PF 300 Flow Gel is a high-capacity energy gel designed for endurance athletes who need sustained carbohydrate delivery over long distances. Delivering 300g of carbohydrate in one resealable soft flask-style pouch, this advanced endurance fuel is built for marathons, ultra running, long-distance cycling and Ironman triathlon racing. If you’re searching for a high-carb energy gel for ultra events, the PF 300 Flow Gel offers efficient, flexible fuelling without carrying multiple small sachets.

Formulated with a 2:1 glucose to fructose ratio, the PF 300 Flow Gel supports optimal carbohydrate absorption to help maintain glycogen levels and delay fatigue during prolonged exercise. The flow-style, resealable design allows you to consume smaller, measured amounts throughout your session, helping you better manage your carb intake strategy. It integrates seamlessly into the Precision Fuel & Hydration fuelling system, making it easier to hit higher hourly carbohydrate targets.

Vegan-friendly and free from artificial colours and flavours, the PF 300 Flow Gel is built for athletes who prioritise measurable, performance-focused nutrition. Whether you’re pushing through an ultra marathon or planning your Ironman bike leg fuelling strategy, this high-carbohydrate gel provides practical, concentrated energy when it matters most.
