I'm not sure what that route is.
In general, find somewhere roughly the other side of the circle, and use your outward portion in one direction and your return portion in the other direction! Make sure you get an "Any Permitted" routed ticket.
I've done that a few times, usually finding a place with a bizarre name (e.g. Snodland, Hag Fold etc
) and an inexpensive fare.
