    Expert Review

    Make your own gel in a reusable flask! Reduce single-use packaging, keep fueling simple and fun. I usually make about 3 servings (90g carbs) in a 250mL flask or Open Fuel's 180mL flask. Sometimes I add a scoop of Ultra Fuel drink mix for flavor. Mix with warm water to desired consistency and then refrigerate for a little while. I often fuel with only liquid calories, but I'm finding that in a hot weather ultra I have portions of the day where I crave more plain water and prefer to get my calories from the gel mix.

    This product is for…

    Trail and ultra runners who want to reduce single-use gel wrapper waste and prefer to control carb density and consistency in a single flask. Also suits runners sensitive to GI issues or sweetness who benefit from a neutral, low-preservative formula.

    Worth noting…

    Pairs with Open Fuel drink mix for added flavor to combat palate fatigue on long efforts. Multiple hosts report no GI issues, including during 100K races.
