Take a read...

Reading research is dangerous if you don't apply the information correctly. You may burn more calories for time spent doing an interval workout but if your 10 mile interval ride takes 30 minutes and the 25 mile ride takes 90 you'd have to be burning 3x as many calories per minute on the 10 miler to equal what you burn on the 25 miler.
That's very unlikely to happen, especially the 10 mile ride has a proper warm up, cool down and your rest periods are at an appropriately low effort.
