Hi folks, newbie here, only been zwifting for 5 days on Tacx Flux 2. Was wondering how accurate the calories burned in zwift? I’ve been putting 20-40km or around 1-2.5 hours on saddle. In the real world, for 2 hours training I would’ve burned around 1200-1300 cal. Using Garmin Edge 520 plus, cadence + HRM strap. In zwift for 2.5 hours ride, I’ve only burned around 800kcal.
I havent compared it directly with the Garmin indoor since I cannot wear 2 HRM strap at the same time… At least I dont think its doable. However, I have compared it to my huawei watch. Both reports same average HR. BUt at the end of the ride, zwift shows I burned around 600ish kcal and the watch shown 800ish kcal with indoor cycle mode selected on the watch.
Just how accurate the calories burn numbers in zwift based on your experience? Which one I should use as benchmark for my diet? Thank you
