Er yes...
But not sure if can actually make it or squeeze it in between Highlands 1200, Wessex SR (I've only done the perms - I want to do the calendar). I've been thinking about BCM as well. I'm interested in group DIY if dates right but am slow on hills but doggedly relentless elsewhere, so I tend not to see much of people after 100k except in passing. It would be nice to know some other blighter was out there enjoying Shawn's "roads with better views".
I did speak to Manotea at the AAAnfractious and he has Jonah's track for potential use as DIY by GPS, and he validated Jonah's ride I believe.
