Absolutely. I didn't mean to imply anything other than respect for this, or the OP.
A colleague is doing LEJOG this summer, and put the mileage (one way) at 1200. I guessed his wasn't the most direct route, but in my head I was concerned that screenman might say '240'.
Attainable, I'm sure, but a lot more frightening than our (comparatively) reasonable 185
