How far/fast do you ride?

I am trying to take all this in

That Garmin screenshot shows calories burned. How does it calculate this? Is it based on heart rate, or just a best guess?

1100 calories for 24 miles means Im screwed I think. lol

average speed*distance*climb= educated guess calories used

Don't know really but as a guide the the Garmin training centre seems quite well respected.

Im checking out a site called Live Strong which seems to have diet planning, route planning and calorie control all in one. That formula makes sense.
