1700kcal in 2½h of cardio is not a ridiculous number, it's possible. Generally the calorie expenditure estimate is pretty inaccurate though. There's a lot of estimating being done and it's all based on the numbers you input and your heart rate.

>An accurate estimation of caloric expenditure requires the following input:
>Resting heart rate (HR rest)
>Maximum heart rate (HR max)
>VO2 max
>Weight
>Age
>Gender

If your resting HR. maximum HR and VO2 max weren't inputted by you but are being estimated by the device, then it's bound to be a lot more inaccurate.
