If you are riding faster than they are walking why not announce that you are passing on their left and proceed with caution? I know.....yield to them, but I doubt that means that you have to travel at a snails pace behind them all day. If they are riding a trail worthy animal that is not spooked at the blowing wind, you should be able to pass them as you would anyone else on the trail.
