It's more likely (to me) that Weiss in fact slowed her own pace, or perhaps just wasn't putting in the effort at the start and that in fact none of them were actually trying, they were rushing yes, but at the same timen they'd have no reason to go all out, and if there was then Ruby, Weiss and Blake would have all used their semblance. In terms of unmodified speed Weiss MIGHT BE faster, though she is almost certainly less conditioned (the same goes for Adam and Blake who can likely attribute their higher endurance and agility to their Faunus nature considering their basis (or speculated basis in Adam's case). When semblances and weapons are involved Ruby is however, far and away, the fastest character we have seen to date.

Except Weiss is very uptight and does considering being late on her first day a travesty. I doubt she would slow down for anything and it might be that everyone else caught up to her, maybe because she ran out of breath or something.
