Sod it. I'll just go for the trial and error method. Add a good bit of 'buffer' distance to compensate for various software used (ViaMichelin, Autoroute and Google Maps), enter and ride and then submit gps file. If it's under distance I will have had a good training ride but will do the Ditchling Devil again as a back up. Just don't want to collect 'kin receipts.
