Well, you've saved yersel' some money so why not just ride the Deeside Loop audax in May instead? 200km taking in Cairn O'Mount and Glen Shee.
Or Snow Roads 300km at the end of June taking in the aforementioned climbs as well as Cabrach and The Lecht.
Or I'm planning on riding Kirrie - Tomintoul - Kirrie at some point this year. Climbing goes something like this:
Glen Isla (easy), Glen Shee (not easy), the bit between Glen Shee and The Lecht (not easy), The Lecht (not easy), The Lecht (not easy but different in the other direction), the bit between The Lecht and Glen Shee (still not easy), Glen Shee (easier than going the other way but not easy), Glen Isla (probably a lot more difficult after all the rest).
I'll be riding it as an audax so I shall be stopping a few times. Total distance about 220km. I have no idea when I'll be riding it, but "not soon". Maybe August.
There also a 300km ride in June starting in Portmahomack going upto Durness and back again, which should provide some stunning scenery.
Total cost for entry for these rides is £21.00 plus £2 per events for non-audax members. So,£29.00 for all four.
And there's me who said I wouldn't mention audax
