Drink Mix 24 Serving Bulk Bag by Open Fuel — One simple drink mix with enough carbs and sodium to fuel all of my training and racing. My favorite flavor is Passion Mango Tango. I also use Naked flavor (light sugary taste) when I want to fuel with liquid calories but avoid flavor fatigue.
Gel Mix Bulk Bag by Open Fuel — 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.
