But, the only real answer is to ask your examiner ahead of time.

As far as I can tell, the following would be a legitimate XC by the
regulation:

Day 1: CDW-AUG (286 miles)
AUG-CDW
Day 2: CDW-4N1 (10 miles? 15?)
4N1-CDW

My point is that it appears that any 250+ mile trip will likely yield a
valid XC if combined with other flights from other days. And that seems
contrary to the spirit of the regulation, at least how I grasp it. After
all, why not simply require the 250 mile flight, or something along those
lines?
