To the OP, riding every day will not help you lose weight. Recovery is every bit as important as the effort-- I am living proof. I did 70 consecutive riding days without a break last year, covering about 2,500 miles and climbing 100,000 feet. My weight remained static. Because to fuel that kind of effort, you have to eat... a lot. It's like the body is in distress all the time. This year I've finally started to take it easy (a little) with planned recovery days as well as just spontaneous days off. Dropped over 10 pounds. I restrict quantity, not individual items. I still eat donuts and all of the other junk-- just less of it.

Climbing a steady grade of 5% or more, at or near threshold, 130 calories per mile. So still yeah, 260kcal isn't a whole lot, but burning 260kcal in less than 10 minutes will still take it out of you.
