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, Power-to-Weight (W/kg), mechanical work (kJ), estimated VO2max (peak and ride average), and a full power graph. Settings, your way: • Rolling resistance: enter your tire's rated wattage and pick your terrain to scale it to what you're actually riding on - or skip the watts and just pick a terrain for an instant estimate • Aerodynamics: pick your riding position - no wind-tunnel numbers required • Wind: automatic or manual entry - pick a compass direction, no need to know the exact degrees • Fully customizable training zones, rider weight, and bike weight
