I rode the Spring into the Dales Audax on Sunday (lovely weather - lovely scenery) and one of the guys there had done the Fred Whitton and the Dales Grimpeur before and he said the Dales Grimpeur was much harder. I've not done either so I think I've maybe let myself in for a rather taxing day
. I was hoping to do it on a 34x23 or 39x25 (I think they're about the same ratio?). Am I being a bit naive?
