Newcomer to zwift as I start to rebuild my confidence on the bike after an injury.
I have my bike rigged up to a Cycleops Fluid 2, and Garmin speed and cadence 2 sensors. My HR is transmitted from my Garmin Venu.
I just had a great ride doing the welcome Fondo workout. But my calorie measurements are way off. Garmin is 588 zwift 398. Which should I trust? And why might this happen?
