I am keeping that weekend free to do the organisers version of the Auld Alliance 400km event but....
If I manage to do it any sooner (late March maybe) I might ride a DIY400 (*) to York just to join in the post event revelry, but I cant commit to an arrow.
* With no 22 hour rule, and a time allowance nudging 28 hours I could adopt a more congenial and gentelmanly approach.
