Got the OK for the DIY so I'll be on that instead.
(BTW, the justification for doing this and not the KVR is that I've got to be home for 8pm, which I can't guarantee to do if I'm on the KVR. The 5am start time for my DIY ride does allow this. Given the choice I'd much prefer to ride a full Calendar event than a DIY+calendar, or DIY.)
