Route - Wandsworth to Great Portland Street

I cannot recommend this lot highly enough: http://www.cyclestreets.net/

Great for finding your way to unfamilar places or even discovering a better commute. Gives you the option to select quiet routes, fastest route or mix etc. Streets ahead of TFL equivalent. Also available as iphone app. Sure it must be on Android too.

Yes, CycleStreets is the best. Accept no substitutes.
