Declare your airport as the start and finish. Then:
The first turn is 50 km to the north.
Second turn is 50 km to the south. Total is now 150 km
Third turn is 50 km to the north, but 10 km away from 1st turn. Total
is now 250 km.
And a return back to the airport yields 300 km.

I haven't tried this but my reading of the sporting code
seems to support this interpretation, to the best I can tell.
I intend to do this for the 300km Gold distance, and think this
will allow me to complete the task without ever flying more than
50km from the start/finish. It also means, if I land out, my
aero-retrieve will cost under $100.


Anyone who has submitted a claim like this and had it
denied, please tell us why...
