A bit of thread resurrection here. I did the C2C from Workington to Newcastle a few years ago, staying as much as possible on the off road sections. Despite a lack of hill training and being a fat bloke, I managed it without dying. The Old Coach Road and Hartside did come close to causing heart attacks though, if it wasn't for the fact I was ridding with some really competitive people I would have walked a lot more of it. In retrospect, i would have ridden on semi slicks rater than full nobblies and would have upgraded from my £300 heaviest hardtail in the world award winning bike. To be honest, my fear of hills has not gone away to this day. Good luck on your trip, I loved it now I get a chance to look back.
