Before revision:  In this new regime URLanism achieves a "ratchet-like" gradient climbing behavior unexpected from mean field theory, and drift speeds much faster than previously believed possible .
After revision:  In this new regime URLanism achieves a "ratchet-like" gradient climbing behavior with drift speeds that can approach half the maximum run speed of URLanism. Our results thus show that the classical drawback of run-and-tumble navigation --- wasteful runs in the wrong direction --- can be mitigated by exploiting the non-normal dynamics implicit in the run-and-tumble strategy .
