Martin Price contacted me the other day with his GPS plot of the C2C. It’s for an all road route. Martin does the ride in a day (not advisable for us mere mortals). You may be interested to have a look. A write-up for all three can be found here, with the 2010 version being data logged on a Garmin Edge705.

I think that the Calder Clarion CC is planning on making this an annual event so anyone interested should get in touch.
