Just one more quick clarification:
"3 turnpoints" is NOT the same thing as a "Triangle"! You can declare
up to 3 turnpoints for many distance tasks and there is no requirement
for them to be in the shape of a triangle. So your "Out and Return"
_course_ is possible, just not as an "Out and Return" type
declaration.
As others have suggested, check out the SC3 and this handy booklet on
the SSA website - its long but it describes the various types of tasks
and turnpoints well:

(you may need to read it two or three times for it to all make sense,
but stick with it)
Good luck,
