Can anyone explain this?
Maybe its the difference between "slow twitch" and "fast twitch" muscles. The effort required from the push off may have better developed "fast twitch" in your left leg. The kind of muscles required for fast explosive anaerobic exercise. But they're no good for endurance, anaerobic stuff.
You've got a sprinter's left leg, and a marathoner's right!
You'll have to push off with the right leg for a month or two
