Anyone have a link to London maps with contour lines?

Whilst London is fairly flat I'm interested in finding the odd hill or two to stretch the legs.
Does anyone know if there's any online map service that shows contours or spot heights for London streets?
I've tried a google search, but the results are poor (finds other people asking the same question) and my usual web sites don't have heights on them.

Where in London are you? There's enough of us in this neck of the woods to point you in the right directions.
The areas that I was thinking about (bike or run) was that side roads off Herne Hill through to Denmark hill that would seem quite steep, although short. Also Richmond
I normally use runningahead.com to record bike routes and runs, and although it uses google maps and has a really nice planner it doesn't have that elevation feature. It seems that you each site has a nice tool, but not the whole set.
Any of the roads off to the right of Honor Oak Road have some pretty steep climbs, or continue on towards Sydenham / Crystal Palace for more "hills" (or as close as you get to them in London)!
Gypsy Hill is a good one, along with Knights Hill in Norwood, both offer a short and sharp kick!
College Road leading towards Crystal Palace Parade offers a couple of ways of torturing yourself as you can either head up College Road and then turn off before it becomes Fountain Drive, or way on up Fountain Drive and try your luck with the roundabout at the top :-)
A bit closer to me you have Cypress Road which is stupid steep and used to form part of one of the more torturous training runs back in the days when I was a Croydon Harrier, thankfully I managed to duck out of those runs :-D
The drag from Elmers End to Crystal Palace is a good run and I'm sure I remember Greg66 mentioning a hill reps route he used to do in the area so it might be worth PM'ing him about it.
As for planning Bikehike is one of my favourites as it has the OS maps and can show a elevation profile for the route as well, that allows you to highlight climbs and they are then shown on the map!

South London - Going along Lordship Lane through Dulwich is quite steep. Or Greenwich Park cycling up Maze Hill/Crooms Hill.
Think how stupid the average person is.......
half of them are even more stupid than you first thought.
Tithepitshaw Lane in South Croydon... (15%?)
There is another in Whyteleafe that allegedly goes over 20%
I think you'll want to check out Sucombs Hill for some punishment in the Whyteleafe, the sign at the bottom claims a 25% gradient!! Did it in the car and thought it was bad at the start until I turned a corner and found the STEEP bit!!! Have yet to return on 2 wheels though :-)
