sadly the lack of miles in my legs, and loss of the ability to digest ridiculous quantities of food at frequent intervals meant I only made it half way (the flat half). Thus I flaked out in the porch of Premier inn (it was full up and icba to trek round further), Lincoln, until someone threw their chips at me "how old are you?" was as withering as I could muster at 2:xx a.m. . I repaired to the 24hr McD next to the uni instead and was the only person there over the age of 25, apart from the staff, of whom thumbs up to one of them who checked I wasn't actually ill etc.
So for Sunday I made do with NCN647* or somesuch from Lincoln to Retford for a mainline train Northwards (it's great if you don't mind a gravel track once it splits off from the NCN64*). Alas for me most trains don't stop at Retford so with that and delayed trains thus missed connections, it took me most of Sunday to get the rest of the way.
Saturday was lovely though, apart from a headwind when I turned N at St Ives, saw both friends as planned and had a couple of enjoyable catch-ups.
*if planning on using, be ware I may have misrememebred the #. iirc, NCN64 goes to Newark and includes Lincoln.
