You mean play a single hole?
This has been from short tees with standard greens as long as I can remember, apparently a "guest" set-up playable with Starters. It's not really useable as a practice ground.
I played OLY this way for the first time before it was opened and it made me think "easy course" :)
Looking for a wee challenge? Play any genuine course "practice", "3 holes" (two clicks to the left) and choose the set-up to your liking (no championship green speed though).
