The PF 300 Flow Gel is a high-carbohydrate fuelling product designed to deliver 300g of carbohydrate in a single resealable pouch, allowing athletes to fuel more efficiently during longer sessions.
It uses a 2:1 glucose (maltodextrin) to fructose ratio, helping support higher carbohydrate delivery during endurance exercise. It is designed to be poured into a bottle or flask and sipped over time, rather than taken as individual gels.
It contains no electrolytes and no caffeine, so hydration needs to be managed separately.

This is not your typical gel, it’s an absolute monster of a fuelling system!
Instead of carrying multiple gels, you’ve got everything in one pouch, which you can decant and sip as needed. That makes a big difference when you’re trying to stay on top of fuelling during long endurance sessions.
Who it’s for:
Endurance athletes doing long runs, rides or events.
Anyone targeting higher carb intake (60/90g+ per hour)
Athletes who want a more structured fuelling approach.
Those who prefer sipping fuel rather than taking gels.
What it does:
Provides a large, easily managed carbohydrate source.
Uses a dual-carb system to support higher carbohydrate uptake.
Allows more consistent fuelling across a session.
Reduces reliance on multiple single-use gels.
How I’d use it:
This is for longer sessions where fuelling becomes critical.
I’d decant it into a bottle or soft flask and use it to hit a specific carbohydrate target per hour. For shorter sessions, it’s overkill, but for longer endurance work, it’s a very efficient way of staying fuelled.
Just remember, there are no electrolytes in this, so hydration needs to be planned alongside it.
The Science:
Oxidation of combined ingestion of glucose and fructose during exercise
Study: Investigated whether combining glucose and fructose increases carbohydrate oxidation compared to glucose alone during endurance exercise.
Journal of Applied Physiology, 2004
https://pubmed.ncbi.nlm.nih.gov/14657042/
Co-ingestion of glucose and fructose significantly increased exogenous carbohydrate oxidation compared to glucose alone, supporting the use of dual-carb systems to improve fuel delivery during prolonged exercise.
Multiple transportable carbohydrates enhance gastric emptying and fluid delivery
Study: Compared glucose-only solutions to glucose + fructose combinations, assessing gastric emptying and fluid delivery during exercise.
Scandinavian Journal of Medicine & Science in Sports, 2010
https://pubmed.ncbi.nlm.nih.gov/19000102/
The addition of fructose to glucose improved gastric emptying and fluid delivery, supporting the use of multiple carbohydrate sources for better tolerance and delivery during endurance exercise.
