    Who it's for
    Endurance athletes who need high-carb fueling during long training efforts and racing without GI distress. Works for both winter and summer use, though one host notes the lower sodium content suits lower-sweat conditions particularly well.
    What people are saying
    Hosts consistently praise the 40g carbs per gel, easy consumption, and stomach-friendly formula. Strawberry Lime and Orange are the most-cited standout flavors, with no notable criticism across the notes.
    Worth noting
    Texture is thicker than a liquid gel but still smooth. A glucose/fructose ratio is credited for GI tolerance; hosts suggest two per hour as a practical dosing rhythm.

    Jack Mislinski, Ultra Runner / Running Coach

    High-carb formula with great GI tolerance thanks to a balanced glucose/fructose ratio. This is 40g and has to be my go-to gel cuz of that... 2 per hour is a sweet spot. Perfect for high-output sessions, and an athlete favorite that's trusted heavily by the SWAP squad... and who doesn't believe David and Megan?

    These are some of my favorite gels for training and racing. The texture is thicker than a liquid gel but still smooth and easy to consume. Strawberry Lime and Orange are excellent flavors. I especially reach for these during the winter months because their lower sodium content aligns when sweat loss is lower.

    Emily Keddie, Ultra/Mountain Runner and Coach

    It's the high carbs and ease of taking it in that does it for me. Quick fuel, non-offensive flavor. It takes the work out of fueling which is paramount when you just need to focus on flowing through the miles.
