Forerunner 35 calorie calculation wrong

Former Member

Hi,

I just upgraded from a forerunner 10 to forerunner 35 and my calories for exactly the same run have gone down by about 300. 

8.1 miles in 1hr 6mins with forerunner 10 it is giving me 960 calories, forerunner 35 gives me 660. I checked my height/weight settings and they are exactly the same. 

I tend to believe the forerunner 10 is the correct one for me - 5'7" 145lbs. Are there any settings I can change on the F35 to make it closer to what F10 is showing me? 

I see others have reported similar issues, but no solutions.

Thanks.
