I just got a decent set of maps last night, there is a maze of small roads running along the coast - so the first step will be to plan a reasonable route, and then work out targets from there. At the moment I reckon I'll be good for at least 120 miles (200kM) per day, I've done this before in/around the Dolomites. If there is an official route and record I'll aim to break it. I live in Ireland and I've been through most of it - so it won't be a research journey for a book on quaint Oirish ways ye boy ye, it will be a balls out record breaking or setting ride.
120 miles a day, with less than 5 hours riding a day then?
