    This will be one of my main fuel sources during Western States. I love the neutral taste, and find this product sits well for a long (but hopefully not too long ;)) day

    This product is for…

    Endurance athletes doing long efforts who need to hit high carbohydrate intake (around 90g/hr) without carrying large quantities of individual gels. Particularly suited to ultra-distance running and similar events.

    Worth noting…

    The consistency is described as thin but not liquid. The resealable pouch is a practical differentiator for long efforts where partial dosing may be needed. Notes are one-sidedly positive with no reported downsides.
