that used to be one of my routes, Stamford Hill followed by the one up toward Camden, happy days getting slowly fitter, that Stamford Hill one was always taxing though, I'd get up it quicker and quicker but was generally ever so slightly knacker at the top and would actually slow down on the flat bit, that strange wasteland of concrete and tower block leading to Finsbury Park
