I was partly joking. I live in Beckenham and work near Waterloo so cycle some of those hills on a daily basis. But citing Dog Kennel Hill as being tough, it's over in 30 minutes!
I was out in Kent this morning doing some proper hills, like Ide Hill and Sundridge Lane. They are really tough; the Micra was struggling near the top even though I'd emptied the boot before we set off.
