Slightly OT but does anyone have a link to the Guinness requirements? I did a quick search but didn't find them.
As far as I know - anecdotally from various sources - they are: Single bike frame, barring accidents; No drafting assistance; Start each day at yesterday's finish point; Need for a tracker? The UMCI need one, and Kasja has one, so I expect Guinness require it. Plus the ride logging and reporting procedures and associated bureaucacy.
I see Kajsa has had a few motorised transfers of not very far - for example she was not feeling well on the ride down to Malvern last week. I imagine the purpose of this rule is to stop people from choosing a route that starts at the top of a mountain, and ends at the coast and riding down it day after day, returning to the top each time by motorised transport. So I expect the short transfers (and her plans to go to continental Europe in the summer) are not affected by this.
The no-drafting rule is understandable enough. But it's a very significant difference between Guinness and UMCA. And it's a bit odd that Guinness have recognised Kurt's record with this disparity. Kasja said she was drafting (er ... I mean ... "composing") an email to Guinness to seek clarification.
It's hard to understand the reasoning behind the single bike rule. For example, if there were to be some hard winter weather, a rider might want to get out for a few miles on ice tyres, but a road frame wouldn't have clearance. And when it comes to servicing, Kajsa will have to have big-ish jobs like BB or headset service done overnight.
