Built for Serious Endurance

Not a calorie counter. A complete fuel logistics system for athletes who need to know exactly what to eat, when, and how much to carry.

You Define What Matters

Track carbs and sodium for high-carb fueling, or add fat and protein for keto. Set min/max targets per hour—overall or per segment. Your strategy, your metrics.

Plan → Execute → Review → Refine

Apply plans to events. Track actual intake during execution. See where you hit targets and where you deviated. Refine for next time.

Smart Route Import

Connect Ride With GPS for public or private routes, or upload any GPX file. Waypoints and POIs automatically become segment markers—just pick which ones matter.

Resupply Shopping Lists

Self-supported? Get a shopping list for every stop. Know what to buy, the weight you're adding, and how long it'll last.

Sweat Test Analysis

Log sweat tests across conditions. Get personalized fluid and sodium recommendations based on temperature, intensity, and your body's data.

Units Your Way

Metric, US, or Imperial. Grams or ounces. Kilometers or miles. Works the way you think, wherever you are.

How It Works
