Well, in my opinion, Peach is a trashy, classless s!ut compared to the regal, elegant Zelda. Peach can probably run faster in her dress because she has a lot of practice running in her dress while fleeing from her fat, abusive, Italian "boyfriend."Peach runs acceptionally well and she wears a dress.
And, since Peach is such an airheaded lamebrain, she probably doesn't have nearly enough class to realize that maybe she shouldn't be running and leaving nasty sweat-stains in what is most likey a dry-clean-only dress. Plus, Peach is probably a little more on the athletic side than Zelda is, since she wastes her time with all sorts of sports and such, whereas the fair, feminine Zelda spends her time actually ruling and taking repsonsibilty for a kingdom, instead of sending her boyfriend and his sibling to do the bidding.
So, in conclusion, Zelda = classy = beautiful, expensive dress = less manueverability= less running
Peach = not as classy = poofy, gaudy, barbie-pink dress = i'm too spoiled and dumb to realize that I shouldn't be running in this dress = more running
ps. i don't actually hate peach, its just fun to make wild accusations and assumptions as if they are real people o .^ but it sorta makes sense, right? zelda is more level-headed and adult than peach in a lot of ways, so maybe thats why they run/move differently?
