I don't think I ever did the Invicta 200, though I did the 300 and 400 a couple of times each. There was a 600 as well, wasn't there? I think I entered it once but DNS due to injury/illness. [ETA: cross-posted with rob]
I did the Kent Corners a few times - the only audax I have ever won (thanks to the chap who left Westgate ahead of me getting lost on the final leg). Plugging the gaps in the calendar in Kent was one of the reasons I started my event last year, but now we've got a glut, with a couple of other new 200s from the Fairies, thanks to Bob and Tim. I'm in the early stages of planning another 200 and possibly a 300 as PBP qualifiers next year too.
As for this being MoK's 9th year, I was forgetting it didn't run in 2016.
