I have only done this route from Cannary Wharf to West Ham, so am half guessing.
Your half-guessing was entirely correct. :-) Thanks!
Did the route this evening, and it's absolutely lovely. A little slow for the morning ride, as it has some rough patches on the path, and a few of those raised-cobble sections where you have to get off and walk for a short time, but it's a very pleasant route indeed for the ride back at the end of the day.
I'll post up the route later if anyone's interested.
