"Oh Shit" moments...

Fucking hate cycling up Kingsland Rd...

Start off at the bottom serene as you like, get to stokey and am fucking livid. Peds don't give a fuck, too many hipster douches erratically trying to steer whatever shitheap douche bike they have bought on a whim, shite road surfaces and fucking maniac bus drivers.

Had a massive swear-fest at about 6 different people on my up there today. fucking tossers.

I ride that route a lot and don't recognise your description of it. It's much like any other main road as far as I can tell.
Apart from the road surface, I agree about that, especially around Dalston.
