Totally unscientific experiment, but for me, walking or cycling I barely break a sweat for short to moderate distances/times.
Only if we're talking about longer distances/times do I start to feel even a small amount of exertion.
In contrast, even a short run (say, 2 miles, or 20 minutes) I am out of breath, sweating like crazy, and totally exhausted.
In other words, unless I am spending a lot of time walking or cycling, I don't feel like I've exercised at all. Whereas even a short run is hard. So if I have a limited time window to exercise, I feel running is a more efficient use of that time?
