For about two years people on the Sheffield Forum have been debating which is the steepest street in Sheffield. Blake Street is apparently the winner. Definitions matter, it is the steepest street (ie with houses along it) but other roads may be steeper. Anyway, today I thought I would see how difficult it was. The answer, not very difficult. It is steep, but it is not particularly long, so the cumulative effect of oxygen debt doesn’t have a chance to build up.
