It surprised me but you're right DiabloScott. Left foot forward on coasting feels natural but right forward felt awkward. Out of the saddle balanced with right foot forward was even worse. I think it's just habit, just what we're used to, and can be trained out.

I know that in martial arts, the small amount of experience that I have, we're trained leading with either foot. After a short while it's natural and you don't even think about it. On sprinting or jumping I lead off either foot interchangeably, but not cycling. I believe it's because I've done it one way for years ... but now I'll switch out.

(looigi, I find that outside foot down is more stable in turns because all my weight is in one spot, not shifty between pedals. And also I get more stroke when I start to straighten up and pedal again)
