Take the guesswork out of endurance fueling. **FuelPacer** is an intelligent Connect IQ data field that dynamically models your carbohydrate burn in real time—replacing rigid, time-based alerts with precise, work-based fueling metrics. **Key Features** * **Dynamic Glycogen Modeling:** Calculates your instantaneous carb burn rate (g/hr) using live power output relative to your FTP, with an automatic Heart Rate Reserve (HRR) fallback when riding or running without a power meter. * **Live Deficit Counter:** Tracks your running carbohydrate deficit in grams so you know exactly when and how much to eat before glycogen depletion impacts performance. * **At-a-Glance Visual Cues:** Color-shifting UI elements immediately alert you when your deficit enters critical thresholds. * **Garmin Connect FIT Integration:** Automatically logs total carbs burned, burn rate, and deficit curves directly into your Garmin Connect activity graphs for detailed post-workout analysis. * **Screen & Device Optimized:** Ultra-low memory footprint with high-contrast layouts tailored for clear visibility across both solar MIP and high-brightness AMOLED displays in 1-field, 2-field, or 4-field grid configurations. Built for cyclists, triathletes, marathoners, and ultra-endurance athletes who want to optimize race-day nutrition and prevent bonking.
