Select routes

Is this still possible to use Zwiftprefs to ride specific routes like :
Handful gravel
Neokyo Critcourse

Thank u

Both are event only routes.

But there is no event coming on these routes …
What is the way to get the corresponding badge

Nothing found on Handful of Gravel route (search for 3 days only).

Use zwifthacks for search.

Edit - next Tuesday and Thursday:
