In the Forum you run west along the north side to the Temple of Saturn (stop 5), turn around at the Capitoline, and come back east down the Sacra Via to the Arch of Titus. On the Palatine you come up the ramp into the gardens (stop 10) and work south, leaving by the far gate.
It also happens to run in rough chronological order once you are on the hill: huts, then Augustus, then Domitian's palace.
