Road routes near Elgin

I dont often post here but quite often post on Singletrack , Anyhoo Im heading up to see my folks In Elgin late next month and was looking for some recommended routes near Elgin. Distance wise anything around 50 - 60 miles and preferably with some hills. I normally take a mtb up there but will be travelling by train so Im going to be riding from my Mums house In Elgin.

Any advice is appreciated.
