but his power meter said 1400. that's more like 40 calories per mile.
funny thing is that I have my Garmin thinking I'm 100# lighter than I really am (i.e. target weight) and it came up with 1900 calories burned. maybe I have to tell it I'm a 98-pound weakling??
That sounds about right, with my experience with my powertap. You did 2.6 hours ( with some climbing) so that is about 538 cals per hour, (I like to use cals/hr) which is pretty good. I think to get to 5-600 c/h is a fairly hard effort. I am assuming you are on some sort of MTB not a skinny tired road bike, since that has less rolling resistance etc which would result in a lower cal burn. To get to 7-800 cals per hour that is race pace and I don't think most people could keep it at that pace for an hour.
