What time of day are you planning this? Running along the south bank can be awful, unless you like dodging people!
I ran that route (or parts of it at different times) a lot when working in London. I mostly stayed on North bank as it was quieter and easier to just get into a rhythm and run, rather than getting caught in bottle necks and having to dodge people.
On the north, you have to come away from the river briefly around St Paul's. But think it's pretty well signed with arrows for riverside path. You also have to leave the river a Parliament (also a very busy stretch) and as Bear says at Battersea. Though you can lose some distance here by running along the A308 (new king road) which I found quite nice to run along with some bars and shops to look at! From Putbey Bridge to hamnersmith definitely run along the south bank as it's nice, easy and off road.
On the south bank, Tower bridge to vauxhall is easy to follow, interesting, but is busy (unless you're going early in the morning). I found I was pushed away from the river at Vauxhall, but I think it was due to building works. Maps certainly show the riversides walk here. No experience it running Battersea to Putbey on the south as I always went North here due to fitting in with my distance plans better!
