Richmond > Covent Garden... Route suggestions?

Route by car is Balls Pond > Essex Road > Angel > Euston Road > Marylebone > Westway, but the last 2 sections are out of the question for cyclists, I suppose. Looking at the map, I can't seem to find a decent way to cut that bit out. Help a newb!

if you want a fast route then you are not far off. Certainly Euston -> Marylebone is fine for cycling and is quick. From there, don't take the flyover of the Westway but bear left down to the roundabout by paddington. Second exit onto the A404 and through the scary looking but quick underpass. Then Harrow road up to the junction with Ladbroke Grove, turn onto Cambridge Gardens and then to Latinmer Rd.

If you want a slow, irritating but traffic free route then the canal is worth a pop. It'd drive me insane though.

Playing with traffic FTW.
