I am an athlete, but not an extremely fit one. I do cycling, 5-10 hours a week.

On a good weather day, I can leave the house on the bicycle, ride for 2-3 hours at a casual/slightly-brisk pace, and burn as much as 1500 calories in a day. I bring a light snack & a bottle of water, but i don't go crazy with "nutrition" - just a granola bar & water.

Not putting down crazy numbers either, averaging maybe 80 watts / hour for 2-3 hours. I do this once or twice a month.

That doesn't add up. Cycling for 3 hours at 80 watts should only burn about 860 kcal, not 1500.

I went back & looked at my most recent "long ride" this fall to see for sure - and you're right. my avg wattage for this ride is 108 ; 80 watts is what I usually do when riding with someone else, ie socially, so that was the ballpark figure I used.
