agree absolutely.
If you honestly believe that a nonweight bearing activity like recreational easy cycling is equivalent to comparable effort recreational easy running in terms of calorie burn and adaptation to the training, you're free to believe that.
Again, you don't need to have detailed peer reviewed studies for this sort of obvious stuff.
You're getting awfully vague with the term 'calorie burn'. I agree most runners burn calories at a higher rate than most cyclists (although the numbers for competitive athletes would be very similar for equivalent duration races)
while exercising. What's not obvious is that the effect lasts for more than an hour or so after exercise. Sure you might get an extra 30-60 Cals of expenditure but there there isn't any evidence that one's resting metabolic rate increases due to running.
If weight bearing exercise was so stressful I would expect to see some muscle hypertrophy which doesn't happen for distance runners.
