I reckon the CVMBC is tougher than the Pennine X. It’s a good route and a great day out. It is really well organised and the cakes at the end were terrific.
There’s some tough climbs but nothing too technical from what I remember. I’m not the fittest bloke on a bike and managed to get around in about four hours.
I’d recommend elbow and knee/shin pads. My mate managed to launch himself on the last section of the north loop and ended up with four stitches in his elbow. It ruined our planned night of boozing in Keswick. :-(
