XC Virtual Power

XC Virtual Power estimates your real-time cycling power from GPS speed, elevation grade, wind, and your bike's physical properties - no power meter needed. On-screen during your ride: • Color-coded 7-zone power gauge with a live needle showing exactly where you sit relative to your FTP • Current and average power, peak power, live VO2 estimate After your ride in Garmin Connect: Normalized Power, Intensity Factor, Training Stress Score, Variability Index, Efficiency Factor, mechanical work (kJ), estimated VO2max, and a full power graph. Settings, your way: • Rolling resistance: enter your tire's rated wattage (from a standard rolling-resistance test) or just pick your terrain (Asphalt/Mixed/Trail) for an instant estimate • Aerodynamics: pick your riding position (Upright/Fitness/Aerodynamic) - no wind-tunnel numbers required • Wind: automatic (from the Weather API on your paired phone) or manual entry for a steady headwind/tailwind • Fully customizable training zones, rider weight, and bike weight
