"We run, you walk."

Translation: Noi alergăm, voi umblați.

[OwlLasers]

Why is, "Alergăm, umblați," incorrect?

[Luchtmens]

While grammatically correct and understandable, your sentence does not emphasize the contrast between "we" and "you". A Romanian speaker would most probably use it less often than the same sentence with explicit pronouns. You may report it, however; it should be accepted.
