    Who it's for
    Endurance athletes doing long training efforts or racing who need high carbohydrate intake and prioritize GI tolerance. Note 2 flags it as especially useful in winter when sweat loss — and thus sodium needs — are lower.
    What people are saying
    Hosts consistently praise the texture as smooth and easy to consume, the flavor (Strawberry Lime and Orange stand out), and the high-carb formula with good GI tolerance. No criticism appears across any of the five notes.
    Worth noting
    Contains 40g carbs via a glucose/fructose ratio designed for GI comfort; hosts cite two per hour as a practical target. Lower sodium content is a specific caveat to weigh in hot conditions or high-sweat efforts.

    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?

    Marisa Romeo, Mental Performance Consultant

    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.
