Whenever I have landed at Luton (Rw 26) in a 737 we have always hit around the 1500ft mark and always clear the runway at the 5500ft point where the last taxiway is. We are usually at taxi speed about 500ft before. Easyjet 90% full plane most of the time.
This gives a ground run of 3500ft with healthy (but I suspect not max) braking.
On the ACE runway which is almost 8000ft this must have been a landing at least half-way down or even more, in other words well past the TDZ.
