If I may add to this... I have found that about 87% of the walkers on a bike path do not seem to kn ow the difference between "right" and "left." And be wary if you see a person on one side of the path and a dog on the ot her side. There is probably a long leash between them that will ruin everyo ne's day if you run into it on a bike.

Tom when on a bike path and passing anything living thing not in a car
when on my bicycle I do these things
I. 1st I don't attempt to break Lances Land speed Record on a bicycle. 2. I assume I am just trying to get from pint A to B at a leisurely pace and ride at that pace. 3. So when I approach horses or dogs with owners about I yell out Hello Horse or Hello Dog. 4. If the owner turns around a bit and acknowledges me I assume it is really safe to pass but at a slow pace. 5. If just a person of couse you use The Passing on your Left shout out. And watch to see if person moves over. I also watch their feet. If feet start moving over to my side I nearly stop to see next move. 6. For horses I shout out early and load. Than I really wait to see what rider will do. 7. Always have a bail out plan. That is why I slow down a lot when any living objects appear on the bike path If I want to ride fast than I do it on the road or when bike path is empty.
