I finished Waverley (in the UK) Waverley, England - CityStrides yesterday - easily my biggest one to date with 1808 streets and 543.3 miles so lots of rural country lanes that actual make for quite a few “fairly normal” runs.
The road I did last (Barhatch Lane Barhatch Lane - CityStrides) features a 21% incline to finish so you probably can see why I had “left” that one 
Ironic though as the location is about as far removed from a “city” you can get round by way.
That’s my 3rd “big” city in the UK finished. I had actually finished 3 smaller ones in Portugal but some “extra” roads were then added. I hope to tick them off on my next visit which fortunately is quite soon.
