If the joggers are in the bike lane it may be illegal, especially if they're running the wrong way. For example, where I live it's a violation of state law 349.232, and it's a lot safer to force them on the sidewalk than it is for me enter the automotive lane of traffic. Rather than taking the time to explain that to a jogger heading my way, I just wait until they are about 20 feet out and I give them a blast from the 'ol Air Zound. You'd be amazed who quickly they realize the extent of their trespass and jump back on to the sidewalk after they hear that. It works on drunks walking the wrong way in the bike lane too.
