GPS watch calories burned?

[sannesley]

I reckon 40 calories per mile is as good as any other guess.

This is what I'm going to work on from now on. If this is the case then my forerunner watch grossly overestimates the calories burnt. I know there are loads of issues to consider such as hills, wind direction, weight of bike etc.. but 49 calories per mile is a quick and ready figure to work with.

I'd go with 30-40 depending on terrain, effort, your weight etc

Those things are nonsense...my Garmin tells me I burnt 2000 cals on an 85 mile sportive and yet the day after when I weigh myself I've put on 2lbs.....crazy

That could just be waterweight
