Not unusual. As a runner, you're supposed to run against the direction of traffic. I used to run in the roads all the time- it's softer and has less obstacles than the sidewalk. We don't have bike lanes here, but I imagine it'd be the same if we did.

Of course runner ettiquette would be to get out of the way if you see a vehicle (car or bike) coming toward you, particularly if they don't have a lot of space to move.
