Being perverse, I should say that the FIA only do motor
racing.

You want http://www.fai.org/sporting_code/sc3_2003.pdf
Rule 1.4.3d (i) and 1.4.3d (ii) apply for 1000k records,
see also the definition of CLOSED COURSE 1.1.15.

Such a course is okay for distance records, 3.1.41
implies that it's also good for speed records.

However, if you are after a 1000k diploma rather than
a record, any 1000k course with 1,2 or 3 pre declared
turnpoints, at least 10km apart, rounded in any order,
would do (1.4.5b).

have seen it, but can't find it.

Thanks,
