MapMyRide has a calorie counter but I don't believe it. Doing some research here I find some old threads on it, but, I am wondering what people's thoughts are on this.

My ride yesterday, 25.3 miles at exactly 16.0 mph. 1:32

MapMyRide says 1412

http://www.caloriesperhour.com/index_burn.php tells me I burned 1818 calories; boy this seems like a lot.

http://www.kreuzotter.de/english/espeed.htm which has a lot of data input and takes into consideration drag in the form of rolling resistance and projected frontal area tells me I burned 1002 calories, which seems a lot more realistic.

And, lastly http://www.bikeforums.net/showthread...light=calories tells me about 824. This seems like the most reliable.

That sure seems like a huge discrepancy between the three sites.

Any thoughts?
