After climbing up most of Cliftonwood, the descent down Granby Hill will come as a relief.
For anyone planning to run this area, there are some really good on-foot options you can't explore by bike -do your research! The Polygon is an on-foot-only option, and there are various flights of steps to get you up or down things.
Speaking of steps, Granby Hill finishes going over the portway and then you can walk or cycle down the steps.
That road should be more fun to ride up when its closed to cars. Quieter.
