If both the camera and subject are moving unpredictably (like a steadicam operator following improvised action), you get good at estimating distances as they change (taking meaurements when possible to verify your estimate). Sometimes a digital rangefinder on the camera (Panatape) can help with this.
For measuring focus at long distances you usually set focus by eye, and you don't typically use very long focal lengths with steadicam or crane shots. But if you do, the standard techniques are used to meaure and pull focus.
