I had a similar experience on my one and only Elstree landing. I had attributed my high approach to 26 to the unusual aspect ratio of the runway (relatively wide) which (now that you mention it) is compounded visually by the up-slope at the western end.
As FFF says, I'm sure there are many more extreme examples of both these runway 'features', but in my limited experience Elstree is the worst.
