Longest regular day bus route in London, in terms of mileage

[cc2005]

What is London's longest regular day bus route, in terms of mileage?

I know there have been threads on here discussing longest routes people have been on, most complicated routes, etc. Some routes have the longest travel time end to end but this is heavily influenced by works, traffic etc.

But simply in terms of mileage, which is London's longest regular day bus route? (do not include seasonal routes or extensions)
Night bus wise I've heard as being the N89.

The 111 or 358 I think.

The X26 and N89 according to LBR - both 34kms long. The 111 and 358 are next in terms of daytime routes. Some night routes (N1, N3, N47, N9) have mileage between the 111/358 and X26.

X26 and N89 are both 21 miles long, but the N89 only achieves this by doing the slade green loop.

X26 - longest regular day route/longest express route (out of three TfL express bus routes).
N89 - longest regular night route/longest regular stopping route.
111/358 - longest regular day stopping routes.
