I was planning to organise a joint fixed and unfixed century forum ride from Garforth. It would seem a bit pointless to do that if you aim to do a fixed-only ride from there at about the same time. Mind you, I suppose I could organise a freehub-only ride over the same route ...
Nah do it together.
I had a quick dabble just now and thought maybe a route taking in the Humber Bridge might be nice. It would probably be more than 100 though. 110 possibly 120 if main roads are to be avoided. It IS flat though so perhaps that would still be OK.
Edit: I think one route came out at 128 miles and something like 2000ft of hills.
Well when I say hills...................
